Impact of Laser Photocoagulation for Peripheral Retinal Degeneration and Breaks on Macular Structure and Function

Peripheral retinal laser photocoagulation can induce foveal hypoperfusion, macular thickening, and prolonged implicit times. Although most of these changes are generally mild and reversible, macular thickening persisted throughout the 3-month follow-up period. Laser parameters, including the number of spots, energy, and distance from the fovea, are associated with macular changes.
