iridotomy

[ī′ridot′əmē]
Etymology: Gk, iris + temnein, to cut
a surgical incision into the iris of the eye. It is performed to relieve occlusion of the pupil, to enlarge the pupil in cataract extraction, or to treat postoperative glaucoma. Topical anesthetic drops are used. An incision is made through the cornea, and a cut is made transversely across the sphincter fibers of the iris. Atropine and an antibiotic may be instilled, and a dressing and shield are applied. After surgery the dressing is observed for signs of drainage. Excessive pain is abnormal. See also iridectomy, iris.

ir·i·dot·o·my

(ir'i-dot'ŏ-mē)
1. Transverse division of some of the fibers of the iris, forming an artificial pupil.
2. Creating a hole in the iris to prevent or treat angle closure glaucoma.
[irido- + G. tomē, incision]

iridotomy

A cutting into the iris.

iridotomy

Creation of an opening in the iris to allow aqueous humour to flow from the posterior to the anterior chamber. It is commonly performed with a neodymium-yag or argon laser (laser iridotomy) in angle-closure glaucoma, especially that caused by pupillary block. See iridectomy; pupillary block.
