Glaucoma is an eye disease characterized by damage to the optic nerve, which is the nerve that transmits visual information from the eye to the brain. It is usually caused by fluid buildup in the front portion of the eye which creates pressure in the eye and damages the nerve. Glaucoma is the leading cause of blindness for people over the age of 60, and any vision lost to glaucoma cannot be recovered. However, with early diagnosis and intervention, treatment can prevent vision loss and blindness.
There are several different kinds of glaucoma and treatment depends on the specific type and severity. The primary goal of treatment is to lower or control the intraocular pressure, or pressure in the eye, which threatens the optic nerve.
