YAG laser iridotomy is a laser surgical procedure used to treat angle-closure glaucoma, a type of glaucoma where the iridocorneal angle is obstructed, preventing proper flow of intraocular fluid. This can lead to increased intraocular pressure (IOP), which can damage the optic nerve and cause vision loss.
During the procedure, a YAG laser is used to create a small opening in the iris, the colored part of the eye. This opening, called an iridotomy, helps relieve the obstruction of the iridocorneal angle and allows intraocular fluid to flow more easily, thereby reducing IOP.
What are the benefits of this procedure?
This treatment has several benefits, including:
- Efficacy: It is an effective treatment for reducing IOP in patients with angle-closure glaucoma.
- Quick and painless procedure: The procedure is performed in the office and takes only a few minutes. Topical anesthesia (numbing eye drops) is used to numb the eye, so there is no pain.
- Safety: YAG laser iridotomy is a safe procedure with few risks of complications.
- Outpatient: There is no need for hospitalization. The patient can return home immediately after the procedure.
- Prevents vision loss: By reducing IOP and relieving pressure on the optic nerve, YAG laser iridotomy can help prevent vision loss and preserve eye health.
Thus, this procedure can be a good option for patients with:
- Angle-closure glaucoma: An acute attack of angle-closure glaucoma is a medical emergency that requires immediate treatment. YAG laser iridotomy can be performed as a preventive treatment to avoid future attacks in at-risk patients.
- Narrow irises: Patients with narrow irises are at greater risk of developing angle-closure glaucoma. YAG laser iridotomy may be a preventive option for these patients.
