Glaucoma occurs when the pressure within the eye increases beyond normal levels. In a healthy eye, fluid drains through a mesh-like organ in the front of the eye and is constantly replaced by new fluid. In those with glaucoma, the fluid does not drain properly, allowing pressure to build up. This increased intraocular pressure (IOP) pushes on the optic nerve, often damaging it. Reduced vision is typically the result. Left untreated, glaucoma can lead to irreversible blindness.
Initially, glaucoma symptoms are subtle and often go unnoticed. For this reason, glaucoma is sometimes called “The Silent Thief of Sight.” Symptoms such as headaches, eye pain, difficulty adjusting to the dark, and deteriorating peripheral vision generally signal the onset of glaucoma.
The best way to avoid vision loss is to have regular eye exams.
