Glaucoma refers to a number of conditions that all damage the optic nerve. Increased pressure in the eye is one of the ways the optic nerve is damaged. Glaucoma is one of the leading causes of preventable blindness.
Often called the "sneak thief" of sight, most forms of glaucoma do not produce symptoms until vision is already severely damaged.
Although glaucoma is most common in adults over the age of 40, susceptibility is not determinde by age alone. There is a genetic component, and those with a family history of the disease and of African descent are at increased risk.
Those with hypertension, diabetes and other systemic diseases are also at risk. Studies have shown individuals at greater risk for glaucoma may fit one or more of the following criteria:
Since early detection is critical to avoiding permanent loss of vision, individuals who possess any of the non-age-related risk factors should have regular examinations by an ophthalmologist every one or two years.
Population should have glaucoma evaluation every two or three years after the age of 40, and every one or two years after the age of 60.
