Glaucoma
Glaucoma is the name of a condition that occurs when pressure builds up inside your eye. If it's left untreated, glaucoma can worsen and seriously damage your eyesight and even cause blindness. The good news is that glaucoma is easy to diagnose and it can be treated.
The key is to find out if you have glaucoma sooner rather than later. The earlier it's diagnosed, the better your chances of successful treatment and preserving your eyesight.
