An iridotomy involves using laser to make a microscopic hole in the iris to prevent the development of acute glaucoma. Acute glaucoma is a painful, sight-threatening condition that may occur suddenly if the angle between certain internal structures of the eye is so narrow that it may suddenly close altogether.
Laser iridotomy is often used as a preventative procedure because of its relatively low risk compared to the potential serious consequence of acute glaucoma.
If an iridotomy is performed early enough it may be the only treatment needed. Some patients, however, still require drops or supplemental laser treatment. Laser treatment has the advantage of being done in the Ophthalmologists’ consulting room with a very low risk for serious complications and minimal, if any, down time.
