Glaucoma is a debilitating condition resulting in damage to the eye’s optic nerve. If unchecked, it may lead to progressive and irreversible loss of vision. It is usually caused by abnormally high pressure inside the eye. This pressure builds up over time when the aqueous humor (clear fluid circulating in the eye) is not drained out properly by the eye.
In a healthy eye, the circulating aqueous humor drains out at regular intervals through a mesh-like channel (trabecular meshwork). In glaucoma, this channel becomes blocked, and the fluid is retained in the eye building up pressure. Therefore, regular eye examination that includes measurement of eye pressure should form an integral component of your visits to the eye doctor.
The goal of glaucoma treatment is to decrease the pressure in the eyes. This is achieved using special eye-drops or medications.
