Late removal of dense posthemorrhagic vitreous membranes following cataract extraction
Modern Problems in Ophthalmology
|January 1, 1975
Abstract:
Severe, seemingly permanent intraocular hemorrhages caused by ocular trauma, Eales' disease and retinal vein thrombosis, lead to late formation of a dense retrolental membrane, vitreous liquefaction and intumescent cataract with faulty light perception. In the absence of ultrasound, the diagnosis was made possible only after removal of the cataract. Lens extraction and excision of the vitreal membrane led to surprisingly good recovery of vision. Three cases are presented and the pathological study of a posthemorrhagic membrane.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
