Laser iridotomy is a surgical procedure used to treat angle-closure glaucoma, a condition where the iris blocks the drainage angle of the eye, increasing intraocular pressure (IOP). The procedure involves using a laser to create a small hole in the peripheral part of the iris, allowing the aqueous humor (the eye's fluid) to flow more freely and reduce the IOP.

Laser iridotomy is a quick, minimally invasive procedure performed under local anesthesia. It is effective in preventing acute angle-closure glaucoma attacks and can provide long-term relief for patients with this type of glaucoma.

The procedure helps improve fluid drainage, reduce IOP, and prevent damage to the optic nerve caused by elevated pressure.
