It s also the biggest risk factor for glaucoma, which is just Alzheimer s disease of the eye.

Today, four decades later, such substances have been used to treat more than 10 million people with neovascular diseases such as macular degeneration and many different forms of cancer.

He did research on astigmatism, glaucoma and other eye diseases, as well as research on correction of visual acuity using eyeglasses and ophthalmological surgery.

More importantly, it makes vision vulnerable to increased pressure within the eye (glaucoma) since this cups and damages the optic nerve at this point, resulting in impaired vision.

Instead of finding out what we thought was the case that blindness was caused mostly by glaucoma and trachoma we were astounded to find out that blindness was caused instead by cataract.

Injury to the optic nerve can be the result of congenital or inheritable problems like Leber's Hereditary Optic Neuropathy, glaucoma, trauma, toxicity, inflammation, ischemia, infection (very rarely), or compression from tumors or aneurysms.

By far, the three most common injuries to the optic nerve are from glaucoma, optic neuritis (especially in those younger than 50 years of age), and anterior ischemic optic neuropathy (usually in those older than 50).
