What is Glaucoma?
Glaucoma is a group of diseases that damage the eye’s optic nerve and can result in vision loss and blindness. With early detection and proper treatment, however, you can often protect your eyes against serious vision loss.
Glaucoma can develop in one or both eyes. Without treatment, people with glaucoma slowly lose their peripheral vision. If left untreated, people may miss objects to the side and out of the corner of their eye. They seem to be looking through a tunnel. Over time, straight-ahead vision may decrease until no vision remains.
Immediate treatment for early-stage, open-angle glaucoma can delay progression of the disease. Therefore, early diagnosis is very important. Glaucoma treatments include medicines, laser trabeculoplasty, surgery, or a combination of any of these. While these treatments can save remaining vision, they don't improve sight already lost from glaucoma.
