Glaucoma
Glaucoma is an eye disease in which the passages that allow fluid to drain out of the eye become clogged. This results in the building-up of fluids, which causes increased pressure inside the eye. This increased pressure damages the optic nerve. The optic nerve is the main carrier of vision information to the brain. Damage to it results in less information sent to the brain and a loss of vision. The exact cause of glaucoma is unknown and it cannot currently be prevented. It is one of the leading causes of blindness in the U.S.
If detected at an early stage and treated promptly, glaucoma can usually be controlled with little or with no further loss in vision. That’s why regular optometric examinations are so important. People of all ages can develop glaucoma, but it most frequently occurs in people:
- Who are over age 40
- Who have a family history of glaucoma
- Who are very nearsighted
- Who are diabetic
- Who are African American
Primary Open Angle Glaucoma develops gradually and painlessly, without warning signs or symptoms. This type of glaucoma is more common among African Americans and Asian males. It can cause damage and lead to blindness more quickly in African Americans, making regular eye examinations, including tests for glaucoma particularly important for African Americans over age 35. Acute Angle-Closure Glaucoma may be accompanied by:
- Blurred vision
- A loss of side vision
- Appearance of colored rings around lights
- Pain or redness in the eyes
Glaucoma can usually be treated effectively by using eye drops. In some cases surgery may be necessary. Unfortunately, any loss of vision from glaucoma cannot usually be restored. Early detection, prompt treatment and regular monitoring can enable you to continue living with normal eyesight.
