Purpose: To report how rhegmatogenous retinal detachment occurred from laser treated lattice degeneration. Methods: We had 9 eyes of 9 patients with retinal detachment during this 3 years, who underwent prophylactic laser photocoagulation for lattice degeneration. We reviewed causes of their retinal detachment. Results: There were two patterns in onset of retinal detachment. Five eyes of 5 patients developed retinal tear at the margin of laser treated lattice degeneration. The patient's age ranged from 29 to 72 years (mean, 56). Retinal tear involved a laser scar in 3 eyes. All the 5 eyes had posterior vitreous detachment (PVD). The remaining 4 eyes developed retinal detachment from atrophic hole within lattice degeneration. The age of the 4 patients ranged from 18 to 43 years (mean, 31). The lattice degeneration and laser spots were detached in all 4 eyes. In one eye, laser scar became retinal hole. Three of the 4 eyes had no PVD and one had PVD. Conclusion: Laser photocoagulation for lattice degeneration appeared to have no prophylactic effect in case of retinal tear with PVD. Three of our 9 cases showed retinal detachment can develop from atrophic hole of laser treated lattice degeneration without PVD.
