Iridotomy is a procedure specifically employed to treat conditions associated with a pupillary block, particularly in the context of angle-closure glaucoma. This surgical technique involves creating a small opening in the peripheral part of the iris, which helps to relieve pressure by allowing aqueous humor to flow from the posterior chamber to the anterior chamber of the eye, thus bypassing the obstructed pathway at the pupillary margin.

In the case of pupils that are stuck in a closed position due to anatomical features or other conditions, iridotomy can facilitate normal fluid dynamics within the eye and mitigate the risks associated with high intraocular pressure, which is a common complication of angle-closure glaucoma. It’s a targeted intervention to restore equilibrium in the eye's fluid system, addressing a critical factor that can lead to vision loss if left untreated. Understanding the mechanism by which iridotomy alleviates the problems associated with pupillary block emphasizes its pivotal role in managing certain types of glaucoma.
