What is the purpose of a laser iridectomy?

The purpose of a laser iridectomy is to create a new passage for aqueous humor drainage in the eye. This procedure is primarily used in the treatment of conditions such as angle-closure glaucoma, where the normal drainage angle of the eye is obstructed, leading to increased intraocular pressure. By using a laser to make an opening in the peripheral iris, aqueous humor can flow more freely, reducing pressure and helping to prevent damage to the optic nerve.

In cases of angle-closure glaucoma, the blockage of the iris can cause a buildup of fluid, which may result in acute symptoms such as severe eye pain, nausea, and visual disturbances. The creation of a new drainage pathway through laser iridectomy allows for improved fluid dynamics within the eye, ultimately preserving vision and preventing complications associated with elevated intraocular pressure.
