Grid laser photocoagulation in the treatment of serous avascular pigment epithelial detachment in age-related macular degeneration.

Purpose: Describe the outcomes of thermal laser photocoagulation in three cases of retinal pigment epithelium detachment associated to age-related macular degeneration. Methods: Three patients with avascular retinal pigment epithelium detachment were treated with green diode laser photocoagulation. Mild macular grid laser application, similar to the treatment of diabetic macular edema was performed after an unsuccessful intravitreal anti-angiogenic treatment. Results: After one year of the laser treatment, two cases reached anatomic resolution, with complete absorption of sub-epithelium serum fluid and improvement of the visual acuity. There was stability of the visual acuity and sub-epithelium fluid reduction, which, however, was partial in the third case. No complications related to the treatment occurred until the conclusion of this study. Conclusions: Macular photocoagulation in grid pattern produced regression of avascular serous pigment epithelium detachment associated with age-related macular degeneration in a short follow-up period. Although long term prospective studies with an increased sample are necessary, it is a method that can be applied in selected patients, with absence of sub-retinal neovascularization or sub-epithelium fibrovascular component.
