What are the symptoms of an angle-closure glaucoma attack?

Symptoms of an acute angle-closure glaucoma attack include severe ocular pain and redness, decreased vision, colored halos, headache, nausea and vomiting.

Because raised eye pressure can rapidly damage the optic nerve and lead to vision loss, an angle-closure glaucoma attack must be treated immediately.

Unfortunately, individuals at risk of developing angle- closure glaucoma often have few or no symptoms prior to the attack. Risk factors for angle-closure glaucoma include increasing age, farsightedness (hyperopia) and Asian heritage. Some early symptoms in people at risk for angle-closure glaucoma include blurred vision, halos in their vision, headache, mild eye pain or redness.

People who are at risk for developing angle-closure glaucoma should have a laser iridotomy. Many common medications, including over-the-counter cold medications and sleeping pills (and any other medication that can dilate the pupil), should be avoided until after the laser procedure is completed. If one eye has an attack of angle-closure glaucoma, the other eye is also at risk and may need treatment.
