Laser trabeculoplasty (LTP) is the application of a laser beam to burn areas of the trabecular meshwork, located near the base of the iris, to increase fluid outflow. LTP is used in the treatment of various open-angle glaucomas. [1] The two types of laser trabeculoplasty are argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT
Trabeculoplasty is a laser treatment for glaucoma. It is done on an argon laser equipped slit lamp, using a Goldmann gonioscope lens mirror. Specifically, an argon laser is used to improve drainage through the eye's trabecular meshwork, from which the aqueous humour drains. This helps reduce intraocular pressure caused by open-angle glaucoma. [1]
In laser suture lysis a red light laser and a contact lens are used to penetrate noninvasively the overlying conjunctiva and cut the black nylon suture. Some surgeons prefer adjustable flap sutures during the trabeculectomy that can be loosened later on with forceps in a slit lamp office procedure.
After two years researchers found that vision and quality of life are similar in both treatments. At the same time eye pressure was lower in people who underwent surgery and in the long-run surgery is more cost-effective. [114] [115] The LiGHT trial compared the effectiveness of eye drops and selective laser trabeculoplasty for open angle glaucoma.

Laser peripheral iridotomy has high efficacy in the treatment of pigmentary glaucoma. Argon laser trabeculoplasty is effective in the management of corticosteroid and pigmentary glaucoma. [2] However, this is often contraindicated due to high rates of failure in patients with uveitic glaucoma. [6] For uveitic glaucoma, treatment with selective ...
