Comparison With Nd:YAG Laser Iridotomy
In acute angle-closure glaucoma cases, surgical iridectomy has been superseded by Nd:YAG laser iridotomy, because the laser procedure is much safer.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 laser created hole in the iris, which facilitates flow of aqueous humor from the posterior to the anterior chamber of the eye.
