Glaucoma is the term for a variety of conditions that damage the optic nerve where it exits from the eyeball, at the optic nerve head. Glaucoma causes progressive loss of sight, beginning in the periphery of the field of vision. The disease is worsened by increased fluid pressure within the eye, and it can usually be halted or slowed by using eyedrops that reduce intraocular pressure. Three million Americans have glaucoma, and >90% of glaucoma sufferers are >45 years old. Glaucoma is the leading cause of blindness in African Americans, who are especially prone to the disease. . .
