This test involves putting drops in your eyes that allow your doctor to see your optic nerve and check for possible damage. If the eye pressure is not within the normal range or if the optic nerve looks unusual, doctors will do one or two special glaucoma tests. One is a visual field test that maps out your field of vision. This test takes some time and requires concentration. The other test is used to check whether the angle where the iris meets the cornea is open or closed.
Treatment usually involves eye drops to lower eye pressure.
Eye drops lower pressure either by decreasing the amount of fluid produced by the eye or increasing the drainage of fluid from the eye. If eye drops are not able to control eye pressure, your doctor may recommend surgery. There are basically two types of surgery for glaucoma. Laser surgery is done with a tiny light beam directed or the drainage site to help it drain better. The procedure is short and generally causes little to no pain.
