Although most people with glaucoma don't lose their sight, glaucoma is still a leading cause of blindness in the United States. It is estimated that only half the people who currently suffer from glaucoma know that they are affect because the disease causes no symptoms until significant damage has occurred. There is no cure for glaucoma but it can be successfully treated, especially when diagnosed early.
Anyone can suffer from glaucoma, but some people are at a higher risk of developing glaucoma: People who are over age 40; People of African descent; People of Hispanic descent; Relatives of people with glaucoma; Very nearsighted people (myopic); People with diabetes; People with extensive steroid use; People with thin central corneas; People who have suffered eye trauma.
Glaucoma is diagnosed by several specialized eye tests including: Measuring the intraocular pressure of the eye (tonometry) Dilated eye exam to check the color and shape of the optic nerve (ophthalmoscopy)
If anything looks suspicious, then other glaucoma tests are necessary such as: Visual field test to measure side vision; Evaluation of the eye’s drainage area (gonioscopy);A test to measure the thickness of the central cornea (pachymetry); GDx to measuring the Retinal Nerve Fiber Layer. The GDx is the state of the art instrument that uses a scanning laser to create an image of the optic nerve. It helps to diagnose and monitor the optic nerve for changes. Most forms of Glaucoma are successfully treated with eyedrops.
