Primary angle closure glaucoma: Once any symptoms have been controlled, the first line (and often definitive) treatment is laser iridotomy. This may be performed using either Nd:YAG or argon lasers, or in some cases by conventional incisional surgery. The goal of treatment is to reverse and prevent contact between the iris and trabecular meshwork.
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
Glaucoma Laser Trial and Glaucoma Laser Trial Follow-up Study: The initial study examined the safety and effectiveness of argon laser trabeculoplasty for treating primary open-angle glaucoma. The results showed that argon laser trabeculoplasty was as safe and effective as using timolol maleate eye drops (the standard treatment).
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]
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 ]
Diode laser with a wavelength of 810 nm is used to perform trans-scleral cyclophotocoagulation. [2] In TS-CPC, the laser absorbed by melanin of ciliary processes causes photocoagulation . [ 6 ] Since it is a painful procedure, TS-CPC is usually performed under retrobulbar or peribulbar anesthesia . [ 2 ]
