Now to the good news. Glaucoma can be managed so that vision loss stops and your remaining vision is protected. The key is diagnosing glaucoma early, before you have lost much vision. Unlike Macular Degeneration, vision loss is peripheral – around the edges – and your central vision remains intact if you are on a treatment program.
The name Glaucoma actually covers a group of eye diseases all involving damage to the optic nerve. In past years, glaucoma was diagnosed by testing the eye’s intraocular pressure (IOP). A high IOP was the criterion for diagnosing glaucoma. That test is still done, but eye doctors have discovered that glaucoma can exist with a normal IOP; and conversely, a person with higher than average IOP may not always have glaucoma. Now the criterion for diagnosing glaucoma is damage to the optic nerve.
