Purpose: To report a case of acquired retinal angioma which developed bullous retinal detachment after transpupillary thermotherapy (TTT). Methods: A 59–year–old woman had a blurred vision (0.5) in her right eye over one month. In the inferotemporal periphery of right fundus, there was retinal hemangioma with 2 disc diameter surrounded by circinate exudates. Fluorescein angiography showed massive dye leakage from the angioma and cystoid macular edema. We applied laser photocoagulation to the feeder artery of the tumor twice but no improvement was obtained. Two months after, we performed cryopexy and scleral buckling for retinal angioma. Subretinal fluid was once absorbed but increased thereafter. Seven months after initial visit, we applied TTT with diode laser (spot size 3.0 mm, power setting 500mW, duration 60sec, delivering 4 pulses). Results: Immediately after TTT, patient complained decreased vision. At 12 days after TTT, bullous retinal detachment was seen and visual acuity dropped to 0.06. Because retinal detachment persisted for 3 months, we applied laser photocoagulation to the angioma 6 times. Then exudative retinal detachment was gradually absorbed and tumor was scarred. Her right visual acuity remained at 0.02 because of macular atrophy. Conclusions: TTT may induce massive leakage from retinal angioma which resulted in bullous retinal detachment. Multiple laser photocoagulation was effective for scarring of the tumor.
