Glaucoma is a common eye disease in older patients in which the optic nerve of the eye is damaged, resulting in vision loss. The progressive loss of optic nerve tissue causes loss of vision. The peripheral vision is usually affected at first. Then as the disease progresses, central vision or even total blindness may occur. Early glaucoma surgery normally involves eye drops that help to lower the eye pressure. Doctor Gipson also uses the SLT Laser to treat glaucoma.
