We read with interest the article by Wallow et al1 presenting clinicopathologic correlation of diode laser burns in a primate model. They provided histopathologic evidence that clinical grade 2 and 3 diode laser burns may induce thermal injury to the deep choroid and sclera. We report a case in which grade 3a burns delivered with a diode endolaser system produced a chorioretinal scar associated with choroidal folds.
Report of a Case.
—An 83-year-old pseudophakic woman developed macular pucker in the right eye following laser treatment for a peripheral retinal tear. Visual acuity decreased from 20/60 to 20/400 OD. A vitrectomy and membrane peeling were performed. During removal of an extensive epiretinal membrane, a small preretinal hemorrhage developed near the inferotemporal vascular arcade. The hemorrhage stopped spontaneously and residual blood was removed with passive suction. Diode endolaser (Oculight SL, Iris Medical Instruments Inc, Mountain View, Calif) photocoagulation was applied to
