Glaucoma - Silent Thief of Sight

Glaucoma – Silent Thief of Sight

Glaucoma is an eye disorder that causes damage to the optic nerve that carries information from the eye to the brain. The increased pressure affects the optic nerve and may cause vision loss.

Two types of classification of glaucoma are open-angle (usually painless) and angle-closure or narrow-angle glaucoma (often associated with pain and redness of the eye). The “angle” in both cases refers to the drainage angle inside the eye that controls the outflow of the watery fluid that is continually being produced inside the eye.

Treatment: Glaucoma usually has few or no initial symptoms.  By the time vision is affected, the damage is permanent. The early diagnosis is key for glaucoma. Progression of glaucoma can be slowed or halted with eye drops, laser treatments or surgery. Researchers has found out that, higher level of exercise appear to provide a long-term benefit of reducing the incidence of low ocular perfusion pressure which is a main factor of glaucoma. Glaucoma development can be reduced by not smoking, maintaining a healthy weight, and eating a varied and healthy diet.
