What Are the Symptoms of Glaucoma?
Only half of people with glaucoma are aware they have the condition. When glaucoma develops, there are usually no early symptoms. This is why glaucoma can "steal" sight gradually.
Symptoms of glaucoma
In its early stages, open-angle glaucoma has no obvious symptoms. As the disease progresses more blind spots develop in the peripheral (side) view. These points can go undetected until the optic nerve has had serious damage, or until it is detected by an ophthalmologist through a complete eye exam.
People at risk for angle closure glaucoma (also called narrow angle glaucoma), usually show no sypmptoms before an attack. Some early symptoms may include blurred vision, halos, mild headaches or eye pain. An attack of angle-closure glaucoma includes the following:
- Severe pain in the eye or forehead;
- Redness of the eye;
- Decreased vision or blurred vision;
- Vision rainbows or halos;
People with "normal tension glaucoma" can have their eye pressure within normal ranges, but show signs and symptoms of glaucoma, such as blind spots in their field of vision and optic nerve damage.
Some people may not have symptoms of glaucoma, but may have a higher than normal eye pressure (called ocular hypertension). These patients are considered as "glaucoma suspects," and should be carefully evaulated by an opthalmologist.
