Glaucoma is a condition that causes damage to your eye's optic nerve caused by increased pressure within the eyeball. Glaucoma is a condition where an accumulation of fluid in the eye increases the intraocular pressure resulting in optic nerve damage. View this sample Analysis (any type) Writer's choice. In a macroscopic hyphema (hyphema), a visible layer of red blood cells in the anterior chamber may be detected even without the aid of slit-lamp magnification. Congenital glaucoma arises mainly due to some structural abnormalities of the drainage system of the eyes. The pathophysiology of glaucoma is not completely understood, but relates to retinal ganglion cell death. Multiple factors acting either on cell bodies or their axons are believed to lead to RGC death. Glaucoma is the second-leading cause of blindness in the U.S. The prevalence of uveitis has been estimated at 38-730 people per 100,000 worldwide. Primary open angle glaucoma 1. People with glaucoma can lose nerve tissue, resulting in vision loss. In general, the terms are usually applied to the eye post cataract surgery. A genetic etiology has also been considered as an explanation for the condition. At present, the term "buphthalmos" is used to describe the visible enlargement of the eyeball detected at birth or soon after, due to any uncontrolled glaucoma in early childhood. In glaucoma, the optic nerve of the eye is damaged, which leads to irreversible blindness. Presentation/PPT.
