Many people think glaucoma is one type of ocular disease. However, it’s a group of diseases that cause damage to the optic nerve. When that happens, people face the risk of losing their peripheral vision and even complete blindness.
There are several categories of glaucoma including open-angle, closed-angle, and normal tension. Open-angle is the most well-known type of glaucoma. It is chronic, slowly progresses, and is caused by an increase in fluid pressure inside of the eye. Often, a person can have this type without knowing it, which is why it is important to have an annual comprehensive eye exam.
As for closed-angle glaucoma, it’s usually painful and it comes on suddenly. In addition, an individual can lose their vision much faster with this kind of glaucoma compared to the open-angle kind.
