Glaucoma is called “the sneak thief of sight” since there are no symptoms and once vision is lost, it’s permanent. As much as 40% of vision can be lost without a person noticing. Glaucoma is the leading cause of irreversible blindness. Moreover, among African American and Latino populations, glaucoma is more prevalent. Glaucoma is 6 to 8 times more common in African Americans than Caucasians.
