Symptoms
of Glaucoma
Most people who have glaucoma don't notice any symptoms until
they begin to lose some vision.
As optic nerve fibers are damaged by glaucoma, small blind spots may begin to
develop, usually in the side -- or peripheral -- vision. The top photo at left
shows how a scene would be viewed by a person with normal vision. The bottom
image shows the same scene as viewed by a person with glaucoma. Many people
don't notice the blind spots until significant optic nerve damage has already
occurred. If the entire nerve is destroyed, blindness results.
One type of glaucoma, acute
angle-closure glaucoma
, does produce noticeable symptoms. In angle-closure glaucoma, there is a rapid
buildup of pressure in the eye (intraocular pressure, known as IOP), which may
cause any of the following:
 | blurred vision
| severe eye pain
| headache
| haloes (which may appear as rainbows) around lights
| nausea and vomiting |
| | | |
Angle-closure glaucoma is a rare, but serious, form of the disease. If you
have any of these symptoms, call your ophthalmologist immediately. Unless
treated quickly, blindness can result.
If you think you're at risk for glaucoma, and haven't had a medical eye
examination in the past two years, you can call the Ismailia
Eye Hospital tm
for
an examination.
