Glaucoma is among the leading causes of blindness in this country, and can be treated when detected early. It is not a disease but rather a circumstance where the optic nerve is damaged over time due to build up of ocular pressure. The pressure develops because of the inability of the eye to release aqueous humor, the clear liquid that circulates within the eye. When vision loss occurs it can be imperceptible, and initially targets the peripheral vision range.

Simple tests detect glaucoma, or the likelihood of glaucoma. The extent and devastation associated with glaucoma cements the need to have annual eye exams after the age of 40. Those at greatest risk include the African-American community, those with family history of glaucoma, those with diabetes, individuals who are nearsighted or using topical steroid drops over the long term, and people over 45 years of age whom have not had regular eye care.
