Overview
Glaucoma is a condition that damages your eye‘s optic nerve. It gets worse over time. It’s often linked to a buildup of pressure inside your eye. Glaucoma tends to run in families. You usually don’t get it until later in life.
The increased pressure in your eye, called intraocular pressure, can damage your optic nerve, which sends images to your brain. If the damage worsens, glaucoma can cause permanent vision loss or even total blindness within a few years.
Most people with glaucoma have no early symptoms or pain. Visit your eye doctor regularly so they can diagnose and treat glaucoma before you have long-term vision loss.
If you lose vision, it can’t be brought back. But lowering eye pressure can help you keep the sight you have. Most people with glaucoma who follow their treatment plan and have regular eye exams are able to keep their vision.
Glaucoma Symptoms
Most people with open-angle glaucoma don’t have symptoms. If symptoms do develop, it’s usually late in the disease. That’s why glaucoma is often called the “sneak thief of vision.” The main sign is usually a loss of side, or peripheral, vision.
Symptoms of angle-closure glaucoma usually come on faster and are more obvious. Damage can happen quickly. If you have any of these symptoms, get medical care right away:
- Seeing halos around lights
- Vision loss
- Redness in your eye
- Eye that looks hazy (particularly in infants)
- upset stomach or vomiting
- Eye pain
