Open-angle Glaucoma

Open-angle glaucoma is the most common form of the disease, and is completely painless with absolutely no symptoms. In the healthy eye, a clear fluid called aqueous circulates inside the front portion of your eye. To maintain a constant healthy eye pressure, your eye continually produces a small amount of aqueous while an equal amount of this fluid flows out of your eye through the trabecular meshwork.

In open angle glaucoma, drainage abnormalities cause the internal eye pressure to increase as fluid builds up, which then deprives the optic nerve of oxygen and nutrients and leads to irreversible optic nerve damage.

The damage caused by open-angle glaucoma is often so slow that patients may not notice any changes to their vision until significant damage has already occurred.
