Acute catarrhal or acute muco purulent conjunctivitis
1) The document discusses acute catarrhal or acute muco-purulent conjunctivitis, listing causes, symptoms, signs, diagnostic criteria, complications, and treatment options.
2) Common causative organisms include staphylococcus, pneumococcus, and adenovirus. Symptoms include redness, discharge, photophobia, and sticking eyelids.
3) Treatment involves washing the conjunctival sac with saline, using mild astringent or antibiotic drops, and avoiding steroids. Homeopathic medicines like Belladonna and Euphrasia are also effective options.
Primary open angle glaucoma (poag)
Primary open angle glaucoma (POAG) is the most common type of glaucoma. It is characterized by an open anterior chamber angle, increased intraocular pressure (IOP), and glaucomatous optic nerve damage and visual field loss. Elevated IOP is the primary risk factor. Treatment involves medical therapy to lower IOP through various drug classes, laser trabeculoplasty to increase outflow, and surgeries like trabeculectomy or newer minimally invasive procedures if medication is insufficient. The goal is to lower IOP enough to prevent further optic nerve damage and vision loss.

Uveitis classification & clinical features 1
Uveitis is inflammation of the uvea, which includes the iris, ciliary body, and choroid. It is classified based on anatomy, clinical course, etiology, and histology. The Standardization of Uveitis Nomenclature (SUN) Working Group developed standardized classifications including anatomical (anterior, intermediate, posterior, panuveitis), descriptors (onset, duration, course), and grading systems. Clinical features depend on the involved area and can include symptoms like pain, photophobia, blurred vision, and floaters. Signs on examination may reveal cells and flare in the anterior chamber, keratic precipitates, hypopyon, synechiae, and lesions of the iris, retina, or
Keratoplasty
This document discusses different types of keratoplasty procedures including penetrating keratoplasty, lamellar keratoplasty, and Descemet stripping endothelial keratoplasty. Penetrating keratoplasty involves replacing the entire diseased cornea and is used for conditions involving all corneal layers. Lamellar keratoplasty replaces only partial layers of the cornea. Deep anterior lamellar keratoplasty removes tissue to the level of Descemet's membrane while Descemet stripping endothelial keratoplasty only replaces the diseased endothelium and Descemet's membrane through a small incision.
Scleritis
Scleritis is an inflammation of the sclera that affects people between 30-60 years old, occurring slightly more in women. It affects 200,000 to 1 million people. There are four types - diffuse anterior being most common, nodular, necrotizing, and scleromalacia perforans. Symptoms include blurred vision, eye pain, light sensitivity, and red patches on the white of the eye. It is normally associated with autoimmune diseases and treated with oral anti-inflammatories or corticosteroids.

Pseudophakic Bullous Keratopathy case
Pseudophakic bullous keratopathy (PBK) is a post-operative condition that can occur as a complication of cataract extraction surgery and intraocular lens placement.
May be manifest in the immediate post-operative period or symptoms may not present for many years.
Conjunctiva
The conjunctiva lines the inner eyelids and front of the eyeball. It has important protective functions and is divided into different anatomical regions. Histologically, it contains epithelial cells, goblet cells that secrete mucus, and a vascular connective tissue stroma. Various inflammatory conditions can affect the conjunctiva including infections, allergies, and autoimmune disorders. Bacterial, viral, and chlamydial infections are common causes of conjunctivitis and can present with discharge, follicles, papillae, membranes, and other signs depending on the specific etiology. Trachoma remains an important cause of preventable blindness worldwide.

congenital glaucoma and congenital cataract
The document summarizes congenital glaucoma and congenital cataract. It discusses the epidemiology, genetics, pathogenesis, clinical features, diagnosis and management of congenital glaucoma. Congenital glaucoma is caused by developmental defects of the trabecular meshwork and anterior chamber angle that obstruct aqueous outflow. Signs include corneal enlargement, Haab's striae, elevated intraocular pressure, and optic nerve cupping. Treatment involves medical therapy with topical medications or surgical procedures like goniotomy to remove obstructing tissue from the anterior chamber angle.
Bacterial keratitis
This document discusses bacterial keratitis, including common pathogens, risk factors, symptoms, signs, investigations, management, and visual rehabilitation. It notes that Pseudomonas aeruginosa and Staphylococcus aureus are common causes. Risk factors include contact lens wear and ocular surface disease. Treatment involves topical antibiotics, with fluoroquinolones or combination therapy used. Steroids may be added after initial antibiotic treatment but are avoided if thinning/perforation occur. Systemic antibiotics are used if systemic involvement is possible. Surgical intervention like patching or keratoplasty may be needed for perforations or dense scarring.
Pterygium & ITS MANAGEMENT
Pterygium is a wing-shaped growth of conjunctiva and fibrovascular tissue on the cornea caused by exposure to UV radiation. It is classified based on its size and involvement of the cornea. Small and asymptomatic pterygia can be monitored, while larger or recurrent pterygia often require surgery to excise the tissue and prevent recurrence. Surgical techniques include bare sclera excision but have high recurrence rates, while conjunctival autografts have lower recurrence but are more technically demanding. Post-operative adjunct therapies like mitomycin C or beta irradiation can further reduce recurrence risk. Complications include recurrence, infection, bleeding, or damage to surrounding ocular tissues.
Ocular surface neoplasia
Benign epithelial tumors of the ocular surface include papillomas, which are caused by HPV infection and can be either pedunculated or sessile. Sessile papillomas have a risk of malignant transformation. Malignant epithelial tumors include ocular surface squamous neoplasia (OSSN), which presents as dysplasia or carcinoma in situ and can invade the cornea or globe if not treated with surgical excision or topical chemotherapy. Neuroectodermal tumors of the ocular surface include freckles, benign acquired melanosis (BAM), and primary acquired melanosis (PAM), which has a risk of progressing to conjunctival melanoma. Close monitoring is important to detect malignant transformation
Corneal Diseases / abnormalities
The cornea can recover from minor injuries on its own. If it is scratched, healthy cells slide over quickly and patch the injury before it causes infection or affects vision. But if a scratch causes a deep injury to the cornea, it will take longer to heal.
Corneal ulcer(bactrial,fungal) 25.02.16, dr.k.n.jha
A corneal ulcer is a loss of corneal epithelium with inflammation caused by bacterial or fungal infection that can lead to blindness if not treated properly. Common causes include infections from Staphylococcus or Pseudomonas bacteria. Treatment involves topical antibiotics like fortified cephazolin or tobramycin drops every few hours to control the infection along with cycloplegic drops for pain relief and prevention of complications like perforation or secondary glaucoma.
Bacterial keratitis
This document provides information on bacterial keratitis including its definition, demographic data, predisposing factors, pathogenesis, symptoms, clinical presentation, diagnostic testing, and treatment. Bacterial keratitis is an infection of the cornea associated with a corneal infiltrate and epithelial defect caused by bacteria. It most commonly affects contact lens users and individuals with ocular trauma or surface disease. Clinical presentation depends on the causative organism, with Gram-positive cocci like staphylococci causing well-defined lesions and Gram-negatives like Pseudomonas typically progressing rapidly. Diagnosis involves slit lamp examination, staining, and cultures of corneal scrapings.
Viral keratitis
Viral keratitis is commonly caused by herpes simplex virus types 1 and 2 and varicella zoster virus. HSV keratitis typically presents as dendritic ulcers or geographic ulcers on the cornea. It can also cause stromal keratitis. Varicella zoster virus causes herpes zoster infection which presents with a painful rash that follows dermatomal patterns, and can also lead to keratitis. Adenovirus is another common cause and presents as punctate epithelial keratitis that may develop into nummular opacities. Treatment involves topical antivirals and steroids depending on the type and severity of infection.
Retinal Vein Occlusion
Retinal vein occlusion (RVO) is an obstruction of the retinal venous system by thrombus formation and may involve the central, hemi-central or branch retinal vein.
The most common aetiological factor is compression by adjacent atherosclerotic retinal arteries.
Other possible causes are external compression or disease of the vein wall e.g. vasculitis.
PERSISTENT HYPERPLASTIC PRIMARY VITREOUS
This document provides information on persistent hyperplastic primary vitreous (PHPV), a congenital eye disorder caused by the failure of the embryonic primary vitreous and blood vessels to regress. It describes the classification, history, clinical features, diagnosis, complications, and management of both anterior and posterior PHPV. Anterior PHPV involves remnants attached to the back of the lens, while posterior PHPV involves remnants arising from the optic nerve; posterior PHPV tends to be more destructive. Treatment may involve surgery such as lensectomy with vitrectomy to clear media opacity and prevent complications like glaucoma.
Ocular surface squamous neoplasiaa.ppt1
This document discusses treatment modalities for ocular surface squamous neoplasia (OSSN), with an emphasis on mitomycin C (MMC). It describes OSSN classification, risk factors, diagnosis, and various treatment options including surgical excision with cryotherapy, chemotherapy with MMC or 5-fluorouracil, and immunotherapy with interferon alfa-2b. Surgical excision with clear margins followed by cryotherapy provides good tumor control but has a 5-10% recurrence rate. Chemotherapy, especially with MMC, is an effective alternative or adjunctive treatment that can help avoid recurrence by treating microscopic disease. MMC has shown good response rates in multiple case examples presented. Interferon al
Infectious Keratitis
The document discusses microbial keratitis, also known as infectious corneal ulcer. It is caused by microorganisms proliferating and infecting the cornea, and is a potentially sight-threatening condition. Bacterial keratitis is the most common type. Risk factors include contact lens wear, ocular trauma, dry eye, and ocular surface diseases. Clinical evaluation involves assessing symptoms, visual acuity, and examining the eye for signs of infection. Corneal scrapings are obtained for staining and cultures to identify the causative organism. Treatment involves topical antibiotics, and sometimes systemic antibiotics or surgery for severe cases.
Trabeculectomy
A surgical procedure featuring a partial thickness scleral flap that creates a fistula between AC and subconjunctival space for filtration of aqueous and creation of conjunctival bleb in an effort to lower IOP
Scleritis1
This document discusses scleritis, an inflammation of the sclera. It defines scleritis and notes it is less common than episcleritis. Scleritis can be classified as anterior or posterior, with anterior scleritis subdivided into non-necrotizing diffuse/nodular or necrotizing forms with or without inflammation. Associated systemic diseases are common in 45% of patients. Signs, symptoms, investigations, and treatment are described depending on the classification of scleritis. Surgical treatment may be needed for extreme scleral thinning or corneal complications.
Corneal dystrophies
This document provides an overview of different types of corneal dystrophies, including their classification, clinical features, histopathology, and management. It discusses epithelial and subepithelial dystrophies, corneal dystrophies of Bowman's layer, stromal corneal dystrophies, and Descemet membrane and endothelial dystrophies. The key points are that corneal dystrophies are inherited, bilateral, and slowly progressive disorders that begin early in life and are characterized by corneal opacification without relationship to environmental factors. Diagnosis involves classification based on the anatomical layer affected and treatment typically involves managing symptoms although surgery may be needed if vision is impaired.

VIRAL CONJUNCTIVITIS Lecture-EKC (1).pptx
Viral conjunctivitis is an inflammation of the conjunctiva caused most commonly by adenovirus. It presents with red eyes, tearing, discharge, and itchiness. While symptoms are usually mild and resolve on their own within 2-3 weeks, adenovirus types 8, 4, and 19 can cause epidemic keratoconjunctivitis, a highly contagious and more severe form. Diagnosis is based on symptoms, and management focuses on relieving symptoms with cold compresses, artificial tears, and topical antihistamines or antibiotics if a secondary bacterial infection is suspected. Good hand hygiene and avoiding touching or sharing personal items are important to prevent spreading the virus.

1. Cataracts - defined as any opacity in the lens that precludes optimal vision. Cataracts are classified based on their location and appearance.
2. Dry eye syndrome - characterized by ocular irritation and visual disturbance due to tear film abnormalities. It is caused by deficiencies in the tear film and treated with artificial tears and ointments.
3. Conjunctivitis - inflammation of the conjunctiva that causes red eye and discharge. It can be infectious (viral, bacterial like gonococcal) or non-infectious (allergic) and is treated with antibiotics, antihistamines or supportive
Eye diseases & disorders
This document discusses various disorders and conditions of the eye. It begins by covering conditions of the eyelids and conjunctiva, such as blepharitis, hordeolum, entropion, ectropion, and ptosis. It then discusses disorders of the cornea and uveal tract, focusing on keratitis (inflammation and ulceration of the cornea), which can be caused by viruses, bacteria, fungi, or trauma. The document also covers conjunctivitis, pterygium, trachoma, and errors of refraction like myopia, hyperopia, and astigmatism as well as other disorders such as cataracts, glaucoma, retinal problems, and eye
Modul SS Mata
An 18-year-old woman presented with red eye that had been occurring for 3 weeks. Her symptoms included itching and recurring episodes that resolved without treatment. Her vision was normal and physical exam found hyperaemic conjunctiva. Differential diagnoses included allergic conjunctivitis. Treatment would involve cold compresses, antihistamines, and short term steroid drops if needed to control symptoms. Preventing recurrence involves staying in cool rooms and using eye drops to inhibit histamine.
cataract.pptx
This document discusses three common eye disorders: cataracts, glaucoma, and conjunctivitis. It defines each disorder and describes their causes, risk factors, signs and symptoms, diagnostic tests, and treatment options. Cataracts involve cloudiness of the lens, glaucoma damages the optic nerve leading to vision loss, and conjunctivitis is an inflammation of the conjunctiva commonly known as pink eye. Surgical intervention may be required for cataracts and glaucoma to prevent further vision impairment.

Dd sudden loss of vision prof munim
This document discusses various potential causes of sudden vision loss, including diseases like venous occlusions, optic neuritis, wet age-related macular degeneration (ARMD), and retinal detachment. For each condition, it lists relevant history, symptoms, possible examination findings, and distinguishing characteristics. The document serves as a guide for clinicians to differentiate between conditions that can cause sudden vision loss.
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.
Unaided vision after manual suture less small incision cataract surgery
Unaided vision after manual suture less small incision cataract surgery (MSICS)
This study assessed the efficacy of MSICS by recording unaided vision four weeks after surgery in 78 patients in Pakistan. The results found that 90% of patients achieved good unaided vision between 6/6 to 6/18, meeting the WHO recommendation of 80% good vision. MSICS achieved excellent unaided visual outcomes and was highly effective in rehabilitating cataract patients. As MSICS is cheaper and less technologically dependent than other methods like phacoemulsification, it is highly recommended for high volume cataract surgery in developing countries like Pakistan.
Blunt Ocular Trauma
Blunt ocular trauma can cause significant visual impairment and is a leading cause of vision loss in young people. In the United States, approximately 2 million eye injuries requiring treatment occur each year, most commonly from sports. Blunt trauma transfers kinetic energy to the eye, altering its shape and creating shear forces that damage internal tissues. Common injuries include hyphema, iridodialysis, traumatic cataracts, retinal breaks, and commotio retinae - a milky white retinal clouding opposite the site of impact. While treatment aims to prevent complications, visual outcomes after blunt ocular trauma are often compromised long-term due to the delicate nature of the eye. Prevention through eye protection is emphasized.
Optic disc swelling
This document discusses optic disc swelling (papilledema) caused by increased intracranial pressure. It presents a case of a 35-year-old woman with severe headaches and vision issues. Examination found bilateral disc edema. CT scan revealed a brain tumor causing pressure. The patient was diagnosed with papilledema from the tumor and underwent surgery. The document then discusses the causes, presentation, stages, histopathology, and treatment of papilledema, emphasizing the importance of an eye exam for patients with headaches to identify potential intracranial issues.
Central retinal artery occlusion
This document presents a case report of a 55-year-old man who presented with sudden vision loss in his right eye. On examination, he was found to have signs consistent with central retinal artery occlusion (CRAO), including a cherry red spot and attenuated retinal arterioles. The patient had risk factors of hypertension and smoking. He was informed that the visual prognosis is generally poor for CRAO presenting more than 48 hours after onset. He was referred to a cardiologist given the risk of life-threatening cardiac complications associated with CRAO. The document then reviews the epidemiology, causes, clinical features, investigations, and management approaches for CRAO, emphasizing the importance of prompt referral for evaluation of underlying cardiac conditions

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Adhd Medication Shortage Uk - trinexpharmacy.com

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.
