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.
