Glaucoma is a chronic disease that gradually reduces eyesight without warning and often without symptoms. If undetected and untreated, glaucoma can lead to irreversible eye damage and eventual blindness. According to the Glaucoma Research Foundation, in the United States glaucoma is the cause of an estimated 9-12% of all blindness cases and is the second leading cause of blindness. Currently, its causes are not well understood and there is no cure.
