Glaucoma is an eye disease that involves damage to the optic nerve, which sends visual signals to the brain. Often called the “sneak thief of sight,” Glaucoma is a disease that strikes without any obvious symptoms. Patients usually don’t even know it’s there until serious vision loss has occurred. And unfortunately, there is no cure for glaucoma. Once a patient has lost their vision, it can’t be restored.
There are several different types of glaucoma. The most common is called open-angle glaucoma (OAG), which accounts for about 80% of all cases. It develops slowly over time, usually after the age of 40. Patients with this type of glaucoma may experience a gradual narrowing of their peripheral vision, which many call “tunnel vision,” or areas of vision loss.
No one knows exactly what causes this damage, but pressure buildup in the eye is proven to be one of the major risk factors associated with glaucoma. When the optic nerve gets damaged by high intraocular pressure (IOP), some signals from the eye aren’t transmitted to the brain. This can result in visual field loss, and if not managed, could eventually lead to blindness.
Glaucoma is one of the most common causes of preventable blindness. Over 3 million Americans have glaucoma, yet only half of them are aware they have it. One out of every five sufferers has a close relative with it. In the United States, approximately 120,000 people are living with blindness because of glaucoma.
The Diagnostic Eye Center can easily measure IOP, and use it as an important clue in the diagnosis and treatment of glaucoma. Here are the case studies related to Glaucoma:
