What is peripheral iridectomy?

Hole in iris. A peripheral iridectomy is a hole made in the outer portion of the iris, usually under the upper lid, which allows direct fluid passage from the back of the eye in conditions in which it might be obstructed. Most commonly it is for a condition termed acute glaucoma but there are other less common conditions for which it is done. It is usually performed using a laser in an outpatient setting.
