Recognizing symptoms

Recognizing the symptoms

The most common from of Glaucoma,Open Angle, starts gradually and gives no warning symptoms, until a very late stage,when much irreversible damage has been done to the field of vision.

Without treatment it can progress to complete blindness.
A much less common from of Glaucoma,Acute Closed Angle,starts with severe pain in the eye,headache,blurring of vision,halos around sources of light,and darkening at the outer edges of your sight (Peripheral vision).

Signs and symptoms of glaucoma
Glaucoma is often referred to as the "silent thief of sight," because most types typically cause no pain and produce no symptoms. For this reason, glaucoma often progresses undetected until the optic nerve already has been irreversibly damaged, with varying degrees of permanent vision loss.

However there are other forms of the disease (specifically, acute angle-closure glaucoma), where symptoms of blurry vision, halos around lights, intense eye pain, nausea, and vomiting occur suddenly. If you have these symptoms, make sure you immediately see an optometrist or visit the emergency room so steps can be taken to prevent permanent vision loss.
