Unlike open-angle glaucoma, narrow angle glaucoma symptoms are sudden and acute.
Narrow-angle glaucoma occurs when the drainage of the front portion of the eye is blocked due to irregular position of the iris. Regardless of the reason why the iris is blocking the drain channels in the anterior chamber of the eye, the rapid build up of pressure inside the eye leads to severe eye pain and eye redness, colored halos around lights, decreased vision, dilated pupil and headache. Many people experience nausea and vomiting. Narrow angle glaucoma symptoms usually last as long as the pressure inside the eye remains high.
In many cases narrow angle glaucoma symptoms are uncommon. The disease progresses slowly and similarly to open-angle glaucoma. In these cases, loss of peripheral vision is usually the first symptom people notice. Some people with chronic narrow-angle glaucoma may have red eyes, blurred vision or headache but these symptoms usually subside with sleep. However, chronic narrow-angle glaucoma leaves distinct signs on the optic nerve appearance and can be picked up during a full eye examination.
