What is Glaucoma?

Typically, in a healthy eye, there is a clear fluid known as aqueous humor in the region between the lens and the cornea. In order to maintain a healthy and constant eye pressure, the eye will produce a small amount of this fluid and at the same time an equal amount of this aqueous fluid tends to flow out of the eye as well. In a person suffering from Glaucoma the fluid is not able to flow out from the eye thereby increasing the fluid pressure inside the eye.

Glaucoma is basically a complicated disease of the eye wherein there is damage to the optic nerve. This damage is progressive and tends to result in complete loss of eyesight in due course of time. In fact, research has shown that Glaucoma is the second largest cause of blindness all over the world. Typically, Glaucoma is not diagnosed in the early stages as there are few or no symptoms of this medical condition in its initial stages. The loss of vision while suffering from Glaucoma tends to occur because the optic nerve that gets damaged is responsible for carrying various images from the eye to the brain of the individual thereby acting as an electric cable that has more than a million wires. Earlier, it was believed that high pressure within the eye is the primary cause of damage to the optic nerve; however it is now known that there are other contributory factors that are responsible for loss of vision on account of Glaucoma. Most cases of Glaucoma that have been diagnosed are open angle Glaucoma whereas in adults alone the commonly observed type of Glaucoma is angle closure Glaucoma.
