laser trabeculoplasty

la·ser tra·bec·u·lo·plas·ty (LTP),

an operation for glaucoma in which laser energy is applied to the trabecular meshwork.

Investigations into laser treatments of open-angle glaucoma began in the early 1970s, but not until the late 1980s was LTP adopted as a standard treatment for the condition. In this procedure, a laser (usually argon) is used to create small openings in the trabecular meshwork at the ocular drainage angle, so as to improve the drainage of aqueous humor and relieve intraocular pressure. Laser iridotomy is sometimes performed at the same time. LTP lessens chances of postoperative infection and hemorrhage, and can be performed on an outpatient basis. This technique has achieved a 2-year success rate of over 70% (dropping to 59% after 5 years), but has been effective only in certain types of glaucoma (especially capsular and pigmentary glaucomas).

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.

laser trabeculoplasty

The use of an argon laser to cut multiple tiny holes in the trabecular meshwork of the eye so as to cause scars that, on contraction, widen the outflow channels of the meshwork and increase the facility of outflow. The method has proved effective in many cases of chronic simple GLAUCOMA.

Laser Trabeculoplasty

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

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.
