Glaucoma Treatment Can Prevent Blindness
Date:7/2/2008

conventional wisdom has been that once optic nerve was damaged beyond a certain point, no matter what one did, the nerve would eventually die, Cykiert said.

"This study shows that's not the case, even people with end-stage glaucoma, if you treat them aggressively and follow them carefully, you can preserve that little amount of vision that's left," Cykiert said.

Glaucoma is a disease that damages the optic nerve, which if untreated will eventually lead to blindness. Glaucoma is detected by an intraocular pressure test. When the pressure climbs above 21 millimeters of mercury, glaucoma is present.

There are several types of glaucoma. The most common in the United States is called primary open-angle glaucoma. In the United States, many people have ocular hypertension, which is a precursor to glaucoma. Ocular hypertension results in elevated fluid pressure in the eye, but no damage to the optic nerve or vision loss.

Blacks and Hispanics are at higher risk for glaucoma, and progression to end-stage glaucoma is very common among blacks.
