This document provides an overview of glaucoma, including what it is, how it damages the optic nerve, risk factors, symptoms, detection methods, treatment options, and current research. Glaucoma is a group of diseases that can lead to damage of the optic nerve and vision loss. It occurs when fluid pressure inside the eye increases and damages the optic nerve over time. While symptoms may not appear initially, untreated glaucoma can result in tunnel vision and complete vision loss. Detection involves eye exams and tests of visual acuity, fields, pressure levels, and nerve examination. Treatment aims to control pressure and prevent further damage through eye drop medications, laser surgery, or conventional surgery. Research continues to study causes, early detection methods

Glaucoma
Glaucoma is a group of eye diseases characterized by increased pressure in the eye due to excess fluid. If left untreated, it can cause damage to the optic nerve and result in vision loss and blindness. The two most common types are open-angle glaucoma, which develops slowly over time, and angle-closure glaucoma, which develops acutely and requires urgent treatment to prevent vision loss. Treatment involves medications or surgery to lower eye pressure and prevent further damage to the optic nerve. Nursing care focuses on administering eye drop medications correctly, providing a safe environment, teaching patients self-care techniques, and ensuring follow-up medical care.

This document provides information about glaucoma, including:
- Glaucoma is a disease of the optic nerve that can cause vision loss and blindness if left untreated. It has no symptoms in its early stages.
- The two main types are open-angle glaucoma, which accounts for 95% of cases, and closed-angle glaucoma, which develops more rapidly.
- Risk factors include family history, age over 40 for African Americans and 60 for others, high eye pressure, thin corneas, and certain medical conditions.
- Regular eye exams including tonometry to measure pressure and examination of the optic nerve are important for early detection and treatment to prevent vision loss. Glau
Glaucoma
This document provides an overview of glaucoma, including its pathophysiology, types, diagnosis, and treatment. Glaucoma is an optic neuropathy characterized by optic nerve damage and visual field loss. It is traditionally associated with elevated intraocular pressure but can occur with normal pressure as well. The two main types are open-angle glaucoma, the most common, and closed-angle glaucoma, which has a sudden onset. Treatment involves medications, laser therapy, or surgery to lower intraocular pressure and prevent further nerve damage.
Glaucoma awareness
Glaucoma is a group of diseases that damages the optic nerve and causes vision loss and blindness. It is the second leading cause of irreversible blindness worldwide. Glaucoma has no symptoms in early stages so many people are unaware until significant vision is lost. While glaucoma cannot be cured, early detection and treatment can help control it and prevent further vision loss by lowering eye pressure through eye drops, laser treatment, or surgery. Lifelong monitoring is important since there is no cure for glaucoma.
Krishna kumar glucoma
Glaucoma is an eye disease that damages the optic nerve and can lead to vision loss and blindness if not treated early. It is usually caused by abnormally high pressure inside the eye, which over time can erode the optic nerve tissue. While some types cause pain and other symptoms, primary open-angle glaucoma typically has no signs or symptoms until vision is impaired, making regular eye exams important. Risk factors include increasing age, family history, eye injuries or conditions, and certain medical issues like diabetes. Treatment options include eye drop medications and surgeries to manage pressure and prevent further damage.
Glaucoma types, Pathogenesis, Diagnosis and Treatment
Glaucomas are ocular disorders characterized by changes in the optic nerve head (optic disk) and by loss of visual sensitivity and field.
There are two major types of glaucoma: open-angle glaucoma, which accounts for most cases and closed-angle glaucoma.
Glaucoma (opthalmology)
Glaucoma is a group of eye conditions that damage the optic nerve, often caused by an increase in intraocular pressure. The aqueous humour maintains pressure in the eye and normally flows through the anterior chamber, draining out of the eye. In glaucoma, the drainage pathways become blocked, increasing pressure and damaging the optic nerve. There are several types of glaucoma including open-angle glaucoma, the most common type caused by slow drainage blockage, and closed-angle glaucoma caused by physical blockage of drainage canals. Treatment aims to lower pressure through eye drops or surgery and slow progression of vision loss.
Ophthalmology assessment questions & answers
1. A 78-year-old woman presents with sudden severe eye pain, red eye, dilated pupil and reduced vision, making acute glaucoma the most likely diagnosis.
2. A 58-year-old man develops a sudden bright red patch on the white of his eye with slight soreness but no vision loss, indicating subconjunctival hemorrhage.
3. When presented with clinical scenarios, the assistant is able to determine the most probable diagnosis from differential diagnoses relating to red eye, sudden vision loss, ophthalmic surgery complications, pharmacological treatments, pupil abnormalities, and visual field defects.

Glaucoma is the name for a group of eye conditions in which optic nerve is damaged at the point where it leaves the eye. This nerve carries information from the light sensitive layer, the retina, to the brain where it is perceived as a picture.
In some people, the glaucoma damage is caused by raised eye pressure. Others may have an eye pressure within normal limits but damage occurs because there is weakness in the optic nerve.
Different types of Glaucoma
Open angle glaucomas (chronic glaucoma): It is most common. The eye is anatomically normal, but blockage or malfunction of the drainage channels slowly over many years causes elevated eye pressure. There is no pain but the field of vision gradually becomes impaired. We need to use chemical cleaner (eye drops) to open the drain or turn down the faucet. If this is insufficient, we can stake the drain (laser trabeculoplasty) & if that doesn’t work. We need to put in new plumbing (surgery / implants)
Angle closure glaucoma (Acute glaucoma): The trabecular meshwork is normal, but the iris is pushed against the meshwork & there is sudden and more complete blockage to the flow of aqueous. It means the drainage channels are covered by a stopper & we need to remove the stopper (laser iridotomy). This glaucoma can be quite painful & will cause permanent damage to sight if not treated promptly. Glued iol surgery in indore with best doctors at glaucoma treatment hospital in indore.
Secondary and developmental glaucoma: When a rise in eye pressure is cause by another eye condition it is called secondary glaucoma. Glaucoma in childhood is called developmental or congenital which is caused by malformation in the eye.
Risk factors

Primary Open Angle Glaucoma
Primary open-angle glaucoma (POAG) is characterized by elevated intraocular pressure, glaucomatous optic nerve damage, and an open anterior chamber angle. It is the most common type of glaucoma and risk factors include older age, family history, and elevated eye pressure. The goal of treatment is to lower eye pressure through medications, laser therapy, or surgery in order to slow the progression of vision loss and prevent blindness. Regular eye exams are important for screening and monitoring the disease.
Grave ophthalmopathy
Graves' ophthalmopathy, also known as thyroid eye disease, is an inflammatory disorder affecting the eye muscles and surrounding tissues that is associated with Graves' disease and hyperthyroidism. Symptoms include bulging or protruding eyes, eyelid retraction, double vision, and potential vision loss if left untreated. The condition results from antibodies that cause swelling of eye muscles and tissues. Diagnosis involves examination of the eyes and imaging tests. Treatment focuses on medications and surgery to reduce swelling and pressure on the eyes.

Glaucoma and cataract include treatment
Glaucoma is a group of eye diseases characterized by increased intraocular pressure, optic nerve damage, and visual field loss. It is a leading cause of blindness worldwide. Cataracts are cloudy lenses that reduce vision and are most often age-related. They occur when the lens becomes less transparent over time. Risk factors for cataracts include diabetes, corticosteroid use, and glaucoma. Both conditions are generally treated surgically by removing the opaque lens or reducing eye pressure, but vision lost from glaucoma cannot be recovered. A combined study found diabetes significantly increases cataract risk while glaucoma is also an independent risk factor, potentially causing 5% of all cataracts.
Glaucoma
Glaucoma is caused by increased pressure in the eye (intraocular pressure) that damages the optic nerve and causes vision loss. It can be primary open-angle glaucoma, angle-closure glaucoma, congenital glaucoma, secondary glaucoma, pigmentary glaucoma, or normal tension glaucoma. Diagnosis involves tests of eye pressure, optic nerve examination, and visual field tests. Treatment options include eye medications, laser surgery, and filtration surgery to manage pressure and slow vision loss.
Diabetic eye disease
Over 112,000 people in Indiana have diabetic retinopathy, which is around 20% of diabetics in the state. About 60% of diabetics receive an annual eye exam, but each year between 12,000 to 24,000 new cases of blindness occur from diabetic retinopathy. Diabetic retinopathy is caused by changes in the blood vessels in the eye and can be detected and treated through annual dilated eye exams and procedures like laser surgery. Maintaining good control of blood sugar and receiving regular eye exams can help reduce the risk of vision loss from diabetic eye disease.
Glaucoma - symptomes and treatment
Glaucoma is a group of eye diseases that damage the optic nerve and can cause vision loss. It is usually caused by an increase in pressure within the eye due to blocked drainage canals. There are two main types - open angle glaucoma caused by partial blockage and closed angle glaucoma caused by sudden, complete blockage. Treatment aims to lower intraocular pressure through eye drops, oral medication, laser therapy or surgery depending on the severity. Surgical treatment is usually a last resort but is the primary approach for closed angle glaucoma emergencies. Post-operative care involves anti-inflammatory and antibiotic eyedrops.
Primary open angle glaucoma
Primary open angle glaucoma (POAG) is characterized by adult onset, elevated intraocular pressure (IOP) above 21 mmHg with an open iridocorneal angle, optic disc cupping, and visual field loss. Risk factors include older age, family history, higher IOP, and certain medical conditions. POAG is caused by reduced outflow of aqueous humor from the eye due to thickening of the trabecular meshwork. Diagnosis requires evidence of optic nerve damage and visual field loss in addition to elevated IOP. Treatment aims to lower IOP and prevent further vision loss through medications, laser trabeculoplasty, or surgery.
118 ophthalmology Questions & Answers - MCQ
This document contains 60 multiple choice questions testing knowledge of various topics in ophthalmology. It addresses topics like retinal layers, causes of blindness in HIV patients, pseudophakia, treatments for myopia, signs of past optic neuritis, definitions of emmetropia and more. The questions cover a wide range of ophthalmic topics including glaucoma, cataracts, retinal detachment, strabismus and others.
Dry eye
Dry eye is a disease of the tear film and ocular surface caused by reduced tear production or increased tear evaporation. It results in eye discomfort, visual disturbance, and potential ocular surface damage. Dry eye can be caused by problems with the lacrimal functional unit such as aging, autoimmune disease like Sjogren's syndrome, or environmental factors. Diagnosis involves evaluating tear production via tests like Schirmer's test and tear breakup time, and assessing ocular surface staining. Treatment depends on dry eye severity and may include artificial tears, anti-inflammatories, punctal plugs, and management of underlying conditions. The goal is to supplement tears, reduce evaporation, stimulate natural tear production, and minimize
Diseases of conjunctiva
The document provides information about the conjunctiva and conjunctivitis (pink eye). It defines the conjunctiva as the thin membrane that covers the eye and inner eyelid. It has two segments: the bulbar conjunctiva covers the eyeball, while the palpebral conjunctiva covers the inner eyelid. Conjunctivitis is inflammation of the conjunctiva that can be caused by allergies, bacteria, viruses, chemicals, or trachoma. Symptoms include redness, discharge, irritation and blurred vision. Treatment depends on the cause but may include antibiotics, antivirals, or surgery. Good hygiene and sanitation can help prevent infectious types.

Senile cataract
Senile cataract is the most common form of cataract affecting people over 50 years old. It involves the development of opaque areas in the normally clear lens. There are two main types: cortical (soft) cataract, which begins at the lens periphery and progresses inward, and nuclear (hard) cataract, which causes the central lens to become dense. Risk factors include increasing age, genetics, UV exposure, smoking, and nutritional deficiencies. Senile cataract causes a gradual loss of vision and symptoms like glare, blurred vision, and colored halos or spots. Surgical removal of the opaque lens is usually required to restore sight.
Ocular trauma
This document provides an overview of ocular trauma, including classifications, signs, symptoms, and management approaches. It discusses various types of trauma such as blunt trauma, penetrating trauma, chemical injuries, and orbital fractures. Key points include:
- Ocular trauma can be caused by physical injury, chemicals, heat, or radiation. It is a leading cause of monocular blindness.
- Trauma is classified based on etiology (accidental, self-inflicted, occupational) and nature (physical, chemical, thermal, radiation). Physical trauma includes perforating, non-perforating, and blunt injuries.
- Complications depend on the type and location of trauma but can include corneal abrasions,
Chalazion
Chalazion is a chronic inflammatory nodule of the meibomian gland in the eyelid. It is the most common benign eyelid lesion, occurring more often in adults. Chalazions start as small, tender swellings and are caused by obstruction and retention of secretions in the meibomian gland. On pathology, they show chronic inflammation with lipid-filled giant cells. Clinically, they appear as painless, hard swellings of the eyelid that can cause blurry vision. Treatment involves warm compresses, antibiotics, steroids, or incision and curettage for larger lesions. Complications include infection, cyst formation, or recurrence.
Conjunctivitis
This document provides information about conjunctivitis (inflammation of the conjunctiva). It discusses the types of conjunctivitis including bacterial, viral, allergic, and others. Bacterial conjunctivitis is the most common type and is usually caused by Staphylococcus aureus. It presents with redness, discharge, irritation and can spread between people. Treatment involves topical antibiotics. The document also covers specific types like acute bacterial, hyperacute, chronic bacterial, and ophthalmia neonatorum conjunctivitis. Chlamydial conjunctivitis including trachoma is also described.
Glaucoma by Dr. Michael Duplessie Ophthalmologist
This document provides information about glaucoma treatment from Dr. Michael Duplessie of Taiba Hospital. It discusses what glaucoma is, who is at risk, types of glaucoma, and treatments including eye drops, laser treatment, and microsurgery. Dr. Duplessie has performed over 10,000 cataract surgeries and 30,000 LASIK surgeries, and organized several major ophthalmology courses and conferences worldwide.
Glaucoma for the students and general practitioners
Glaucoma is a disease of the optic nerve that can lead to irreversible blindness if left uncontrolled. It is often asymptomatic until severe vision loss has occurred. The most common type is primary open-angle glaucoma, which occurs when the eye does not properly drain fluid, leading to elevated pressure in the eye. Treatment aims to lower intraocular pressure through medications, laser treatment, or surgery in order to slow the progression of vision loss. While glaucoma continues progressing even with treatment, the rate of progression is much slower, allowing for satisfactory vision with proper management.

Glaucoma by Dr. Michael Duplessie Ophthalmologist
This document provides information about glaucoma treatment from Dr. Michael Duplessie of Taiba Hospital. It discusses what glaucoma is, who is at risk, types of glaucoma, and treatments including eye drops, laser treatment, and microsurgery. Dr. Duplessie has performed over 10,000 cataract surgeries and 30,000 LASIK surgeries, and organized several major ophthalmology courses and conferences worldwide.
Glaucoma for the students and general practitioners
Glaucoma is a disease of the optic nerve that can lead to irreversible blindness if left uncontrolled. It is often asymptomatic until severe vision loss has occurred. The most common type is primary open-angle glaucoma, which occurs when the eye does not properly drain fluid, leading to elevated pressure in the eye. Treatment aims to lower intraocular pressure through medications, laser treatment, or surgery in order to slow the progression of vision loss. While glaucoma continues progressing even with treatment, the rate of progression is much slower, allowing for satisfactory vision with proper management.
Primary Glaucoma
This document discusses primary glaucoma, including primary open angle glaucoma. It defines primary glaucoma as optic neuropathy with characteristic changes to the optic disc and visual field, mostly associated with increased intraocular pressure. It describes the classification, epidemiology, physiology, clinical manifestations, diagnosis and management of primary open angle glaucoma. It also discusses ocular hypertension and defines it as increased intraocular pressure without optic disc or visual field changes, noting those with high risk factors should be carefully monitored.

Important trials in Glaucoma
The Ocular Hypertension Treatment Study (OHTS) was a landmark randomized controlled trial that showed treating patients with ocular hypertension reduced the risk of developing primary open-angle glaucoma by more than 50% compared to observation alone. Increased risk factors for developing glaucoma included older age, larger cup-to-disc ratios, higher baseline intraocular pressure, and thinner central corneal thickness. The Early Manifest Glaucoma Trial found that treating newly diagnosed glaucoma patients lowered their intraocular pressure by 25% on average and reduced the risk of visual field progression by about 20% compared to no treatment. The Collaborative Initial Glaucoma Treatment Study found that both medical and surgical treatment were effective for initially lowering intra
Glaucoma
Glaucoma is a group of eye diseases that damage the optic nerve and causes vision loss and blindness. It is often asymptomatic in the early stages. The main cause is increased pressure within the eye (intraocular pressure) due to impaired fluid drainage from the eye. There are two main types - open angle glaucoma which develops slowly over time and closed angle glaucoma which is a medical emergency with sudden severe eye pain. Treatment aims to reduce intraocular pressure and halt further optic nerve damage.

Uveitic Glaucoma
This document presents a case study of a 45-year-old female patient with uveitic glaucoma in her left eye. It describes her examination findings and management over time with topical medications, laser peripheral iridotomy, and later cataract surgery with trabeculectomy and mitomycin C to control her intraocular pressure. The document then provides definitions and classifications of uveitic glaucoma and discusses common etiologies including Fuchs' heterochromic uveitis, Posner-Schlossman syndrome, juvenile idiopathic arthritis, herpetic uveitis, and sarcoidosis. It covers pathogenesis, clinical features, investigations and management approaches for these entities.
Normal tension glaucoma
This document summarizes a presentation on normal tension glaucoma (NTG). It begins with an introduction defining NTG as open-angle glaucoma with characteristic optic nerve damage and visual field defects in patients with consistently low intraocular pressure (IOP) below 21 mmHg. It then describes a case presentation of a 47-year-old female patient. The remainder of the document discusses the history, examination, investigations, differential diagnosis, management, pathogenesis involving both IOP-dependent and independent factors, and epidemiology of NTG. Key points are that lowering IOP through medication or surgery can help prevent progression even in NTG, and that NTG may have an underlying vascular component involving low ocular perfusion pressure
Approach to a glaucoma
Glaucoma is a group of eye disorders characterized by progressive optic nerve damage and visual field loss associated with elevated intraocular pressure. A thorough examination of patients with suspected glaucoma includes assessing visual acuity, intraocular pressure, examining the anterior chamber angle, optic nerve, and performing visual field testing. Symptoms of glaucoma depend on the type and severity of glaucoma, and may include visual changes such as decreased vision, colored halos, eye pain, and headaches.

Glaucoma prevention
Glaucoma is a serious condition that involves increased pressure inside the eye and can lead to permanent blindness if left untreated. It is more common in African Americans and tends to run in families. While it causes no symptoms initially, over time it can destroy peripheral vision and eventually central vision without treatment through eyedrops, pills, laser therapy or surgery. Regular comprehensive eye exams are important for early detection and treatment to prevent vision loss from glaucoma.

Glaucoma and OCT – Are Macula Scans More Valuable than Disc Scans
This document discusses the use of optical coherence tomography (OCT) for diagnosing and monitoring glaucoma. It suggests that macula scans may be more valuable than disc scans due to being more repeatable and reliable. It also discusses using ganglion cell complex thickness measurements and progression analysis on OCT to detect damage earlier than visual field tests. Additional techniques like electroretinography and visual evoked potentials can detect even earlier changes in the visual system to aid in glaucoma diagnosis and monitoring treatment effectiveness.

GLAUCOMA PRESENTATION.pptx
Glaucoma is a group of eye conditions that damage the optic nerve. The optic nerve sends visual information from your eye to your brain and is vital for good vision. Damage to the optic nerve is often related to high pressure in your eye. But glaucoma can happen even with normal eye pressure.
Glaucoma can occur at any age but is more common in older adults. It is one of the leading causes of blindness for people over the age of 60.
Many forms of glaucoma have no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is in its later stages.
It's important to have regular eye exams that include measurements of your eye pressure. If glaucoma is recognized early, vision loss can be slowed or prevented. If you have glaucoma, you'll need treatment or monitoring for the rest of your life.

When to see a doctor
If you experience symptoms that come on suddenly, you may have acute angle-closure glaucoma. Symptoms include severe headache and severe eye pain. You need treatment as soon as possible. Go to an emergency room or call an eye doctor's (ophthalmologist's) office immediately.Causes
Glaucoma develops when the optic nerve becomes damaged. As this nerve gradually deteriorates, blind spots develop in your vision. For reasons that doctors don't fully understand, this nerve damage is usually related to increased pressure in the eye.
Elevated eye pressure happens as the result of a buildup of fluid that flows throughout the inside of the eye. This fluid also is known as the aqueous humor. It usually drains through a tissue located at the angle where the iris and cornea meet. This tissue also is called the trabecular meshwork. The cornea is important to vision because it lets light into the eye. When the eye makes too much fluid or the drainage system doesn't work properly, eye pressure may increase.
Open-angle glaucoma
This is the most common form of glaucoma. The drainage angle formed by the iris and cornea remains open.
all about glaucoma
Glaucoma is caused by increased pressure in the eye due to a backup of fluid that over time damages the optic nerve. It is often asymptomatic until vision is impaired. The main types are primary open-angle glaucoma, which is the most common, as well as normal tension glaucoma, angle-closure glaucoma, and others. Treatment aims to lower pressure through medication or surgery to prevent further vision loss.
Glaucoma_ a brief review
Glaucoma is a neurodegenerative eye condition characterized by increased intraocular pressure that can cause progressive vision loss and blindness if left untreated. It is the second leading cause of blindness worldwide. Treatment aims to lower intraocular pressure through prescription eye drops, oral medications, laser therapy, surgery, or a combination of approaches to slow or prevent further vision loss. Regular eye exams are important for early detection and treatment monitoring to help preserve sight.

Glaucoma
Glaucoma is a leading cause of irreversible blindness that damages the optic nerve and results in progressive vision loss. It is often asymptomatic in early stages. Glaucoma is controlled by lowering eye pressure through eye drops, laser treatment, or surgery. Regular monitoring is required long-term to preserve remaining vision as damage cannot be reversed. Risk factors include family history, age, eye injuries, and certain medical conditions. Early detection through eye screening can prevent vision loss from glaucoma.
Glaucoma
Glaucoma is a disease of the eye in which fluid pressure within the eye rises; if left untreated, the patient may lose vision and even become blind.
Genetics of glaucoma
Glaucoma is a group of eye diseases that can damage the optic nerve and lead to vision loss and blindness. It is caused by increased fluid pressure in the eye (intraocular pressure) which can damage the optic nerve. The front of the eye produces fluid that normally drains out, but in glaucoma the fluid drainage is blocked causing pressure to rise. Glaucoma often affects older adults but can occur at any age. Risk factors include family history, age over 40, high eye pressure, diabetes, and eye injuries. Treatment options are eye drops, laser surgery, or microsurgery to improve fluid drainage from the eye.
What is Glaucoma?
Glaucoma is a disease that damages the optic nerve and can lead to vision loss and blindness. It occurs when fluid pressure inside the eye increases because the fluid does not drain well. Risk factors include high eye pressure, older age, African ancestry, and a family history of glaucoma. Glaucoma has no symptoms in early stages but can progress to peripheral vision loss, blurred central vision, and total blindness. It is detected through a comprehensive eye exam including pressure checks, pupil dilation, and visual field tests. Treatment focuses on lowering eye pressure through eye drops, laser surgery, or traditional surgery to slow the progression of vision loss.
Glaucoma
Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often linked to a buildup of pressure inside your eye.
Glaucoma treatment
Glaucoma is the second leading cause of blindness worldwide, affecting over 74 million people, nearly 10% of whom are blind. Prevalence of glaucoma among Indians is between 2.6-4% but only 7% of those affected utilize medical assistance. Glaucoma involves damage to the optic nerve from increased fluid pressure in the eye, resulting in irreversible vision loss if left untreated. The most common type is primary open-angle glaucoma, which has few symptoms and gradual damage, while primary angle-closure glaucoma causes sudden severe eye pain and vision loss. Risk factors include age over 40, family history, ethnicity, high eye pressure, diabetes, and steroid use. Glaucoma is detected through

Glaucoma Presentation for Medical and Pharmacy Graduates
Glaucoma is a group of eye diseases that damage the optic nerve and can cause vision loss. It has no symptoms in early stages. The most common type develops slowly over time from increased fluid pressure in the eye. Left untreated, glaucoma can cause permanent vision loss starting with peripheral vision and progressing inward. Regular eye exams are important for early detection, as treatment can slow the progression if caught early.
Pilocarpine use in glaucoma
Pilocarpine is an eye drop medication used to treat glaucoma by reducing the pressure inside the eye. It works by stimulating muscarinic receptors in the eye, causing the iris sphincter muscle and ciliary muscle to contract. This contraction allows fluid to drain from the eye more easily, thereby lowering intraocular pressure. Pilocarpine should not be used by patients with uveitis or pupillary block glaucoma, or those with an allergy to pilocarpine. Common side effects include blurred vision, eye pain, headaches, and nausea.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Novas diretrizes da OMS para os cuidados perinatais de mais qualidade
Novas diretrizes da OMS para os cuidados perinatais de mais qualidadeProf. Marcus Renato de Carvalho
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.

- 5. What is the optic nerve? The optic nerve is a bundle of more than 1 million nerve fibers. It connects the retina, the light-sensitive layer of tissue at the back of the eye, with the brain (see diagram). A healthy optic nerve is necessary for good vision.
- 6. optic nerve
- 7. How does glaucoma damage the optic nerve? Increased pressure inside the eye causes glaucoma. In the front of the eye is a space called the anterior chamber.
- 8. How does glaucoma damage the optic nerve? A clear fluid flows continuously in and out of this space and nourishes nearby tissues. The fluid leaves the anterior chamber at the angle where the cornea and iris meet.
- 9. How does glaucoma damage the optic nerve? When the fluid reaches the angle, it flows through a spongy meshwork, like a drain, and leaves the eye. Open-angle glaucoma gets its name because the angle that allows fluid to drain out of the anterior chamber is open.
- 10. How does glaucoma damage the optic nerve? However, for unknown reasons, the fluid passes too slowly through the meshwork drain. As the fluid builds up, the pressure inside the eye rises. Unless the pressure at the front of the eye is controlled, it can damage the optic nerve and cause vision loss.
- 12. What are the symptoms of glaucoma? At first, open-angle glaucoma has no symptoms. Vision stays normal, and there is no pain. As glaucoma remains untreated, people may notice that although they see things clearly in front of them, they miss objects to the side and out of the corner of their eye.
- 13. What are the symptoms of glaucoma? Without treatment, people with glaucoma may find that they suddenly have no side vision. It may seem as though they are looking through a tunnel. Over time, the remaining forward vision may decrease until there is no vision left.
- 14. How is glaucoma detected? Most people think that they have glaucoma if the pressure in their eye is increased. This is not always true. High pressure puts you at risk for glaucoma. It may not mean that you have the disease.
- 15. How is glaucoma detected? Whether or not you get glaucoma depends on the level of pressure that your optic nerve can tolerate without being damaged. This level is different for each person.
- 16. View of boys by person with normal vision. View of boys by person with glaucoma.
- 17. How is glaucoma detected? Although normal pressure is usually between 12-21 mm Hg, a person might have glaucoma even if the pressure is in this range. That is why an eye examination is very important.
- 18. Helps in staging of glaucoma
- 27. Can glaucoma be treated? Yes. Although you will never be cured of glaucoma, treatment often can control it. This makes early diagnosis and treatment important to protect your sight. Most doctors use medications for newly diagnosed glaucoma; however, new research findings show that laser surgery is a safe and effective alternative.
- 31. What research is being done? The National Eye Institute (NEI) is the Federal government's lead agency for vision research. The NEI is supporting many research studies both in the laboratory and with patients. This research should provide better ways in the future to detect, treat, and prevent vision loss in people with glaucoma.
- 32. What research is being done? For instance, researchers recently found a gene that causes a form of glaucoma that starts at a young age. This is the first glaucoma gene ever located. This finding could help us learn more about how glaucoma damages the eye.
- 33. What research is being done? The NEI is also supporting clinical studies that will tell us more about who is likely to get glaucoma, when to treat people with increased pressure, and which treatment to use first.

Editor's Notes
- The last decade has seen a rapid acceleration in the understanding of the pathology of glaucoma and its natural history It is a path followed by healthy individuals who subsequently develop ocular hypertension & glaucoma. It is a progression from undetectable disease to asymptomatic disease & then to functional impairment Undetectable disease – occurs at the level of RGCs & optic nerve fibers Asymptomatic disease is detectable by clinicians on examination but not by patients Functional impairment is detected by patient and may lead to blindness
