What a person with glaucoma sees

Are you experiencing problems with your peripheral or side vision? Do you have to turn your head to see what's to your immediate right or left? Do you have blurred vision, nausea, and headaches? Do you see "halos" around bright lights? It might be glaucoma.

Glaucoma is a group of eye diseases that can lead to blindness by damaging the optic nerve. The eye continuously produces a fluid, called the aqueous, that must drain from the eye to maintain healthy eye pressure. Learn more in Glaucoma: An Overview.
