An iridectomy, also known as a surgical iridectomy or corectomy, [1] is the surgical removal of part of the iris. [2] [1] These procedures are most frequently performed in the treatment of closed-angle glaucoma and iris melanoma. [1]
In acute angle-closure glaucoma cases, surgical iridectomy has been superseded by Nd:YAG laser iridotomy, because the laser procedure is much safer. Opening the globe for a surgical iridectomy in a patient with high intraocular pressure greatly increases the risk of suprachoroidal hemorrhage, with potential for associated expulsive hemorrhage. Nd:YAG laser iridotomy avoids such a catastrophe by using a laser to create a hole in the iris, which facilitates flow of aqueous humor from the posterior to the anterior chamber of the eye. [3]
Surgical iridectomy is commonly indicated and performed in the following cases:[ citation needed]
