What is the procedure that uses an Argon laser to shrink areas of the trabecular meshwork?

The procedure that uses an Argon laser to shrink areas of the trabecular meshwork is laser trabeculoplasty. This treatment is specifically designed to improve the outflow of aqueous humor in the eye by targeting the trabecular meshwork, which is responsible for draining fluid from the anterior chamber. By applying laser energy, the tissue shrinks, which can help increase the drainage and lower intraocular pressure in patients with glaucoma.

Laser trabeculoplasty can be an effective option for managing glaucoma, particularly when topical medications are not sufficient or when a patient is not compliant with medication regimens. The Argon laser is commonly used because it provides precise energy delivery to the targeted tissues without significant damage to surrounding structures.

The other options listed refer to different procedures that target various aspects of ocular conditions. For instance, laser photocoagulation generally refers to the use of lasers to treat retinal conditions rather than addressing the trabecular meshwork. Laser iridotomy is a procedure for creating an opening in the peripheral iris to relieve pressure in the eye, particularly in narrow-angle glaucoma. Laser peripheral iridoplasty involves reshaping the iris to improve aqueous outflow, but it does not directly target the trabecular meshwork like trabeculoplasty
