Mooren's ulcer is a rare autoimmune condition characterized by a chronic, painful peripheral corneal ulcer. It is more common in males and older individuals. Treatment involves a stepwise approach starting with topical steroids, then conjunctival resection to remove inflammatory cells, followed by systemic immunosuppressants if needed. Later stages may require additional surgeries like lamellar keratectomy or keratoplasty to promote healing and rehabilitation of the cornea. The goals are to arrest the destructive process and promote reepithelialization of the corneal surface.
Corneal edema occurs when the cornea swells and increases in thickness due to an abnormal accumulation of fluid in the stroma. The key causes of corneal edema include mechanical trauma, glaucoma, contact lens overuse, endothelial dystrophies, and bullous keratopathy. Corneal edema is evaluated using slit lamp examination, pachymetry, and imaging modalities like OCT and specular microscopy which measure corneal thickness and endothelial cell density. Treatment depends on the underlying cause but may include controlling IOP, removing contact lenses, or performing keratoplasty in severe cases.
1. Monocular elevation deficiency (MED), also known as double elevator palsy, is characterized by an inability to elevate one eye in all fields of gaze, resulting in hypotropia of the affected eye.
2. The condition can be congenital or acquired, with causes including superior rectus palsy, inferior rectus restriction, and supranuclear lesions.
3. Surgical management of MED depends on forced duction test results and may include inferior rectus recession, superior rectus resection, or Knapp's procedure to transpose the horizontal rectus muscles. The goal is to improve eye position and increase binocular vision.
This document discusses anterior uveitis, which is inflammation of the iris and ciliary body. Symptoms of anterior uveitis include pain, redness, loss of vision, swelling, and exudate in various structures of the eye. Exudate can appear as cells and flare in the anterior chamber, keratic precipitates on the cornea, and posterior synechiae adhesions between the iris and lens. Increased pressure within the eye can also occur due to exudate, leading to vision loss from glaucoma.
This document discusses various complications that can occur after keratoplasty (corneal transplantation). It summarizes early post-operative complications such as shallow anterior chamber, wound leak, iris incarceration, wound dehiscence, and suture-related problems. It also discusses late complications that can occur months or years after surgery, including graft rejection, infectious crystalline keratopathy, corneal membranes, cataract, astigmatism, glaucoma, and recurrence of the original recipient corneal disorder. For each complication, the document provides details on causes, risk factors, clinical features, prevention strategies and management approaches.

Viral Keratitis: Diagnosis, Management and Latest GuidelinesSahil Thakur
This document summarizes viral keratitis, with a focus on herpes simplex virus (HSV) keratitis. It discusses the epidemiology, pathophysiology, clinical manifestations, and types of HSV keratitis infections including congenital, neonatal, primary ocular, and recurrent ocular infections. It describes the characteristic presentations of HSV epithelial keratitis including dendritic ulcers, as well as various forms of stromal keratitis such as necrotizing, non-necrotizing, disciform, diffuse, and linear keratitis. Complications such as iridocyclitis, trabeculitis, and endotheliitis are also summarized.
Branch retinal vein occlusions (BRVOs) are caused by compression of the retinal vein by an adjacent artery, causing turbulent blood flow and thrombus formation. This leads to retinal ischemia, macular edema, and neovascularization. While BRVOs are typically idiopathic, risk factors include hypertension, atherosclerosis, and thrombophilic conditions. Treatment involves monitoring for complications like macular edema and neovascularization, and using corticosteroids, anti-VEGF agents, laser photocoagulation, or vitrectomy depending on the case. Prognosis depends on how distal the occlusion is from the optic disc, with more distal occlusions having a better visual outcome.
This document summarizes common ocular allergies and their treatment. It discusses the anatomy of the eye and approaches to diagnosing itchy eyes. Common allergic diseases include allergic conjunctivitis, vernal keratoconjunctivitis, atopic dermatitis, and giant papillae conjunctivitis. Allergic conjunctivitis is caused by an IgE-mediated inflammatory response and accounts for many seasonal cases related to pollen. Treatment includes cold compresses, artificial tears, topical antihistamines, mast cell stabilizers, topical corticosteroids, and immunomodulators for severe cases.
This document discusses challenges and new technologies for accommodating intraocular lenses to treat presbyopia. It summarizes several hinged and dual-optic accommodating IOL designs currently in development or clinical trials, including their mean accommodative amplitudes.
