Amblyopia, also known as lazy eye, is a vision development disorder where vision in one eye is reduced if not treated early in childhood. There are several types of amblyopia including strabismus, stimulus deprivation, anisometropic, isoametropic, and meridional amblyopia. Risk factors include premature birth, small size at birth, family history, and developmental disabilities. Treatment involves occlusion therapy to force use of the weaker eye, removing any opacity in the media, and correcting any refractive errors. If left untreated, amblyopia can cause permanent vision loss.

Introduction, Assessment and Management of Amblyopia
Amblyopia, commonly known as a "lazy eye", is a reduction in vision that occurs in one or both eyes due to abnormal visual development during childhood. There are several causes of amblyopia including unequal refractive errors between the eyes (anisometropia), misaligned eyes (strabismus), visual deprivation from conditions like cataracts, and high amounts of uncorrected refractive errors. Amblyopia is assessed through visual acuity tests, refractive error checks, and examinations for eye alignment and movement. Treatment involves correcting any refractive errors, wearing an eye patch over the strong eye to encourage use of the weak eye, atropine eye drops to blur vision in the strong eye, or active visual stimulation therapies
Amblyopia and it's Management
A detailed presentation covering all aspects of amblyopia, a form of cortical visual impairment, defined clinically as a unilateral or bilateral decrease of visual acuity (VA) that cannot be attributed to structural abnormalities of the eye or visual pathway
LOW VISION CASE PRESENTATION
This document presents a low vision case study of a 14-year-old female patient named Juhi Patil. She presented with blurry right eye vision for distance over the past 4 months and itchy eyes in both eyes for 3 months. Her initial examination found dullness and retinal pigment epithelium atrophy in the macula and fovea of both eyes. She was prescribed a bar magnifier and See TV for low vision assistance with near and distance vision tasks. The final devices provided her 6/12p binocular vision for distance with the See TV and near vision of N6 with the bar magnifier. She was diagnosed with macular dystrophy, which was explained as a genetic disorder that deteriorates

Classification of strabismus
This document discusses the classification and terminology used for strabismus (eye misalignment). It defines different types of strabismus such as phoria, tropia, and heterophoria based on the presence of fusion. It also classifies strabismus based on factors like deviation direction, variation with gaze, age of onset, and etiology. Various types of strabismus deviations and causes like paralytic, mechanical, and orbital are described. References for further information on strabismus classification are provided.
Paralytic strabismus
The document discusses paralytic strabismus, including:
1) Hering's law of equal innervation and Sherington's law of reciprocal innervation which are important in diagnosing paralytic strabismus.
2) The sequelae of ocular muscle palsy including overactions and underactions of muscles.
3) Methods for investigating incomitant strabismus including cover tests, motility examination, and Hess screen plots to identify the affected muscle.
Latent squint or (heterophoria)
Latent squint, also known as heterophoria, is a condition where the eyes have a tendency to become misaligned when not being used, such as when one eye is covered, but remain straight during normal use. It occurs when the brain's continuous effort to maintain binocular fusion is removed, such as by covering one eye. Heterophoria is very common and usually does not cause double vision, as the brain corrects for any misalignment. While often asymptomatic, an ophthalmologist can test for latent squint using techniques like the alternate cover test.
Geriatric ophthalmology
This document discusses ophthalmic issues that commonly affect the elderly population. It notes that visual impairment is an important health problem in elderly individuals, with the most common causes being age-related cataract, age-related macular degeneration, and glaucoma. The document provides details on the pathogenesis and treatment of these common ocular conditions, as well as other geriatric ophthalmic problems including dry eye, presbyopia, corneal diseases, eyelid disorders, and ocular surface tumors. Regular eye exams are recommended for early detection and management of vision issues in senior citizens.

Pattern Strabismus | A.V Pattern
Pattern strabismus occurs when there is a change in the magnitude of horizontal deviation between up and down gaze. The most common types are A pattern (convergence in up gaze) and V pattern (divergence in up gaze). Pattern strabismus can be caused by abnormalities of vertical or horizontal muscle action, anatomical anomalies, disorders of muscle innervation, or anomalous muscle insertions. Evaluation involves measuring the deviation in different gazes using cover-uncover testing and Hess screening. Management may involve adaptation or surgery tailored to the specific pattern, which aims to improve alignment and binocular function.

Examples include devices that increase illumination, contrast, size of text, and assist with tasks like reading, writing, medication management, and mobility. Training in techniques like eccentric viewing and scanning can also help low vision patients make better use of their remaining vision.
Amblioppia and it's management
This document provides an overview of amblyopia, including:
- Amblyopia is diminished vision not caused by eye pathology. It is classified by cause such as strabismic, anisometropic, and deprivation amblyopia.
- Treatment involves eliminating vision obstructions, correcting refractive errors, and encouraging vision development in the amblyopic eye through occlusion therapy or penalization of the strong eye.
- Occlusion therapy typically uses eye patches while penalization uses blurring techniques. Regular follow-up is important during treatment, especially for younger children. The goal is to achieve maximum possible vision in the amblyopic eye.
Amblyopia
Amblyopia is a reduction in best corrected visual acuity that cannot be attributed to structural eye abnormalities and results from strabismus, anisometropia, high bilateral refractive error, or visual deprivation. It is primarily a defect in central vision and prevalence is 2-4% in North America. Treatment involves refractive correction, patching or penalizing the better eye to force use of the weaker eye. Prognosis is best when treatment begins early in childhood during the critical period of visual development.

Amblyopia is a partial loss of vision in one or both eyes without any organic disease. It is classified into strabismic amblyopia, refractive amblyopia, and stimulus deprivation amblyopia. Strabismic amblyopia occurs due to squint in one eye leading to less vision. Refractive amblyopia is caused by uncorrected refractive errors such as anisometropia, bilateral ametropia, or meridional astigmatism. Stimulus deprivation amblyopia results from media opacities like cataracts that deprive the eye of visual stimuli early in development. Treatment involves correcting the refractive error or media opacity and occlusion or penalization therapy to force use of the amb
VISUAL DEFECTS IN CHILDREN.pptx
Visual defects in children can be caused by issues affecting the eye, optic nerve, or cerebral visual pathways. Common causes include refractive errors, retinopathy of prematurity, and infections occurring during prenatal development or infancy. As children age, other issues like tumors, injuries, or degenerative disorders may also lead to visual impairment. Specific conditions discussed in more detail include amblyopia, myopia, diplopia, astigmatism, suppression, nyctalopia, strabismus, and blindness.

Amblyopia, commonly known as lazy eye, refers to reduced vision in one or both eyes that results from suppression of the retinal image. It is caused by uncorrected refractive errors like nearsightedness, farsightedness, or astigmatism between the eyes (anisometropia); eye misalignment like strabismus; or visual deprivation from conditions that obstruct the visual axis. Symptoms include misaligned eyes, poor depth perception, eye closing or squinting, and eyes not moving together. Treatment involves correcting refractive errors with glasses or contacts, patching or blurring the stronger eye to stimulate the weaker eye, and sometimes surgery to repair eye alignment issues or remove obstructions.
Amblyopia, Diagnosis and Management
The document discusses amblyopia, including its definition, causes, classification, risk factors, diagnosis, critical period of visual development, and management through eliminating obstacles to vision, correcting refractive errors, and forcing use of the amblyopic eye through occlusion of the better eye or use of cycloplegic drugs. Amblyopia is a potentially reversible reduction in visual acuity that develops due to abnormal visual experience during the critical period of visual development from birth to around age 8.

Refractive error's
This document discusses various types of refractive errors including myopia, hypermetropia, and astigmatism. It defines each condition and describes their causes and symptoms. For myopia, it explains different types such as congenital myopia, nocturnal myopia, and induced myopia. It also lists potential complications of untreated high myopia. Treatment options for refractive errors include glasses, contact lenses, LASIK, and refractive lens exchange procedures. The document is intended to provide information on refractive errors and vision correction.
Amblyopia
Amblyopia, commonly known as lazy eye, is a disorder of sight that results in partial loss of vision without any organic disease of the eye. It is the most common cause of vision loss in children. Amblyopia can be functional, caused by things like strabismus or unequal refractive error between the eyes, or organic, caused by undetectable lesions in the eye or visual pathway. Treatment involves occlusion therapy, penalization, or pleoptic exercises and works best when started in young children under 3 years old. Amblyopia is reversible if treated early but can become permanent if left untreated.
Amblyopia
Dr. Shashidhar Patil presented on amblyopia (lazy eye) at a symposium moderated by Dr. Arvind L. Tenagi. Amblyopia is a common vision problem in children caused by abnormal visual development that results in decreased vision in one or both eyes. It can be prevented or reversed with early intervention before age 8. Treatment involves prescribing corrective lenses, removing any obstructions to vision, and occluding the better eye to force use of the amblyopic eye. Occlusion therapy works best when started early and continued consistently over time with good parental cooperation.
Amblyopia
Amblyopia, also known as lazy eye, is a vision development disorder where one eye fails to achieve normal vision even with glasses or contacts. It begins in infancy or early childhood. There are several types of amblyopia, including strabismic amblyopia caused by eye misalignment, stimulus deprivation amblyopia from conditions blocking vision in one eye, and anisometropic amblyopia due to unequal refractive errors between the eyes. Treatment involves correcting refractive errors with glasses, patching or blurring the good eye to force use of the amblyopic eye, and sometimes using eye drops in the good eye. The goal is to strengthen the vision in the amblyopic eye during the visual development period in childhood
Amblyopia.pptx
The document discusses amblyopia, also known as lazy eye, which is a vision development disorder where an eye fails to achieve normal visual acuity even with corrective lenses. Amblyopia occurs during infancy or early childhood and is usually in only one eye. It is caused when the brain ignores signals from one eye due to unequal visual acuity or clarity caused by a disorder or malfunction in that eye. Common causes include strabismic amblyopia from misaligned eyes, refractive amblyopia from unequal refractive errors between eyes, and deprivation amblyopia from something obstructing light to an eye. Treatment involves patching the good eye to force use of the weaker eye, corrective glasses, eye drops to blur vision in

Amblyopia
1. Amblyopia is a partial loss of vision in one or both eyes without any organic disease, and is caused by certain factors like strabismus, anisometropia, or cataracts during visual development from birth to age 6.
2. The main types of amblyopia are strabismic from squinting, stimulus deprivation from blocked vision, anisometropic from unequal refractive errors, isoametropic from high refractive errors in both eyes, and meridional from uncorrected astigmatism.
3. Occlusion therapy is the main treatment, where the stronger eye is patched to force use of the amblyopic eye, with younger children needing
Eye and ENT.pptx
Pediatric eye disorders can affect vision development in children. A childhood eye exam evaluates visual acuity, ocular alignment and structure, and eye health. The exam includes tests of the red reflex, pupil response, and visual focus and tracking. Common childhood eye conditions include strabismus, amblyopia, and infections like conjunctivitis. Early detection through regular eye exams is important to address any vision problems and prevent long-term amblyopia.

It defines leucocoria as a white reflection seen in the pupil that could indicate an underlying condition like cataract, retinoblastoma, or persistent hyperplastic primary vitreous. The document outlines the causes, presentations, classifications, management, and visual prognosis of pediatric cataracts. It emphasizes the importance of early referral for any detected leucocoria to rule out retinoblastoma or other serious conditions and prevent amblyopia. Overall management of pediatric cataracts aims to restore vision through early surgery and amblyopia treatment for the best possible visual outcomes.
GLAUCOMA
Glaucoma can be open angle or closed angle. Open angle glaucoma includes ocular hypertension, glaucoma suspect, primary open angle, exfoliative, pigmentary, normal/low tension, and congenital/juvenile types. It is assessed using visual field testing, intraocular pressure measurement, gonioscopy, optic disc examination, and imaging like OCT. Treatment involves eye drops like prostaglandin analogs, beta blockers, and surgeries like trabeculectomy. Monitoring intervals depend on whether pressure and disease are controlled. Primary angle closure glaucoma is less common but riskier, requiring treatment like laser iridotomy.
Eye structure and function
The document outlines the basic structures and functions of the human eye. It describes the main eye structures including the lids, cornea, iris, lens, retina, choroid, and sclera. It also details the extraocular muscles that control eye movement and their corresponding cranial nerves, as well as layers of the retina such as the pigment epithelium, rods and cones, nerve fiber layer, and optic nerve. Protection of the eyes is provided by surrounding structures like the orbit, lids, sclera, cornea, and tears.
EXAMINATION OF ANTERIOR SEGMENT OF EYE
The document outlines the steps for examining the anterior segment of the eye, including taking a patient history, performing a systematic examination from front to back using magnification, light, and diagnostic drops. Key areas examined are the lids, lacrimal system, orbit, eye movements, pupil reactions, conjunctiva, cornea, anterior chamber, iris, lens, and anterior vitreous, along with refraction and tests for intraocular pressure and visual fields. Photos show examples of pathological findings that may be observed, such as giant papillae on the eyelid and corneal staining.
COMPLICATION OF CATARACT SURGERY
This document summarizes potential complications from cataract surgery, grouped into those occurring at surgery, within a week, and longer term. Complications at surgery include posterior capsule rupture, dropped nucleus, and small pupil. Within a week, potential issues are infection, high eye pressure, corneal swelling, and inflammation. Longer term risks include cystoid macular edema, retinal detachment, and unexpected conditions found on postoperative exam. The document provides examples and treatment approaches for several common complications.
ANATOMY OF CORNEA
The cornea has several layers:
1. The epithelium is the outermost layer consisting of 5-6 layers of stratified squamous cells that renew from stem cells located around the periphery.
2. The stroma makes up 90% of the cornea and contains collagen fibrils for strength and elasticity.
3. Descemet's membrane is the basement membrane of the endothelium and contains collagen and glycoprotein that can regenerate. It shows Henle fibers on its posterior surface.
4. The endothelium is the innermost single cell layer that decreases in cell density with age. Gap junctions allow for fluid regulation to maintain corneal clarity.
anatomy of eyeball
The eyeball has three concentric layers and is approximately 21-26mm in diameter. It is connected to the brain by the optic nerve and protected by the bony orbit and eyelids. The cornea is transparent and located at the center of the eyeball's anterior surface, comprising 5 layers and measuring approximately 12mm by 11mm. The sclera covers the posterior four-fifths of the eyeball and provides attachment points for the extraocular muscles. Six extraocular muscles control eye movement, with the four recti muscles originating from a common tendinous ring and inserting into the sclera, while the two oblique muscles originate from bones in the orbit.
ENUCLEATION WITH CSR
The document describes the procedures for enucleation and corneo-scleral rim excision. Enucleation involves removing the entire eye globe while preserving surrounding structures, usually due to a painful blind eye, staphyloma, or malignancy. The procedure involves aseptic preparation, peritomy, identification and cutting of extraocular muscles and optic nerve, and orbital packing. Corneo-scleral rim excision is done to harvest the cornea and scleral rim for transplantation. It involves peritomy, scleral incision 4mm from the limbus, separating the corneo-scleral rim from underlying uveal tissue, and storing in preservation medium. Both require consent

MERCURY GROUP.BHMS.MATERIA MEDICA.HOMOEOPATHY
Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

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.
