What Are the Symptoms of Glaucoma?

The early symptoms associated with chronic open angle glaucoma, the most common type, are usually unnoticeable. At first, in most cases, the build up of pressure is gradual without any discomfort or pain. Most people do not detect a change in their vision until substantial sight loss has occurred. Certain parts of peripheral (side) vision are affected first  with the top, sides, bottom of the field of vision becoming decreased. Later, in the course of the disease, central vision becomes affected, mild headaches and difficulty with night vision might be experienced. And, if left untreated, total blindness will result.

The patient stricken with acute closed angle glaucoma experiences more noticeable symptoms. The sudden onset of acute glaucoma can cause blurred vision, severe pain, nausea, and halos around lights. Congenital glaucoma also presents noticeable symptoms in the infant such as enlarged eyes, cloudy cornea, light sensitivity, and excessive tearing.
