Glaucoma - Symptoms
glaucoma vary according to the type of glaucoma you
If you have
open-angle glaucoma (OAG), the only symptom you are
likely to notice is vision loss. Side (peripheral) vision is usually lost
before central vision.
You may not notice side vision loss until
it becomes severe because the less affected eye makes up for the loss. The loss
of sharpness of vision (visual acuity) may not become apparent until late in
the disease. By that time, significant vision loss has occurred.
Closed-angle glaucoma (CAG) may cause no apparent
symptoms or only mild symptoms. You may experience short episodes of symptoms
(subacute closed-angle glaucoma) that usually occur in the evening and are over
by morning, or you may have severe (acute) symptoms that require immediate
medical attention. Symptoms of closed-angle glaucoma usually affect only one
eye at a time and often include:
- Sudden, severe blurring of
- Severe pain. The pain may occur in the eye itself or in
certain areas immediately around the eye. See a picture of possible
areas of pain associated with CAG.
- Colored halos around
- Redness of the eye.
- Nausea and vomiting.
Symptoms of glaucoma present at birth (congenital glaucoma) and glaucoma that develops in the
first few years of life (infantile glaucoma) may include:
- Watery eyes. The baby may also appear to be
sensitive to light.
- An eye or eyes that look cloudy, indicating
that the clear front surface of the eye (cornea) has been
- Eyes that look larger than normal because the eyeballs
have become enlarged as a result of high pressure. This symptom does not occur
- Rubbing the eyes, squinting, or keeping the eyes closed
much of the time.
