laser trabeculoplasty  the placing of surface burns in the trabecular network of the eye to lower intraocular pressure in open-angle glaucoma.

Laser Trabeculoplasty

In this procedure the laser attempts to open the normal drainage channels of the eye so fluid can drain more effectively.

laser trabeculoplasty,

an application of argon or selective laser energy to the trabecular meshwork to increase aqueous outflow in the treatment of glaucoma. The procedure may be recommended when intraocular pressure increases despite administration of topical agents. The eye is anesthetized with a topical anesthetic. The trabecular network is viewed through an antireflective-coated four-mirror gonioprism. A power setting and exposure time are selected to blanch the anterior trabecular meshwork with laser energy without causing bubble formation. A potential complication is a temporary increase in intraocular pressure, which is treated with drugs. The effects of laser trabeculoplasty are not always long lasting.

A procedure aimed at improving the outflow of aqueous humour in open-angle glaucoma by producing a series of laser burns (usually with an argon laser) to the trabecular meshwork.
