Argon laser trabeculoplasty for intractable glaucoma following intravitreal triamcinolone.

Based on experimental and clinical studies performed by Machemer and coworkers and other researchers, intravitreal injection of triamcinolone acetonide (IVTA) has been used as an alternative for the treatment of several diseases of the retina and uvea, such as chronic cystoid macular edema, age-related macular degeneration, and retinal vascular occlusion. However, it is an invasive procedure, with the risks of complications such as raised intraocular pressure (IOP), vitreous hemorrhage, and endophthalmitis. We describe the clinical course of 3 patients who developed secondary open-angle glaucoma following IVTA, uncontrollable by topical antiglaucomatous medication, treated with argon laser trabeculoplasty.
