The authors have experienced a case of Coats' disease treated by argon laser photocoagulation in 17 year-old female who visited to our department becurbance of visual disturbance of her left eye. At her first visit, visual acuity was 1.2 in the right eye and hand motion in the left eye. Ophthalmoscopic examination of ter left eye revealed telagiectatic vascular anomalies associated with massive exudation in the temporal periperal retina and star-shaped hard exdates with edema in macula. Fluoresein angiogram of the same eye showed diffuse capillary nonperfusion areas and leaking dilated tortuous vessels with microand macroaneurysms in the lesion. Argon laser photocoagulation was applicated to occlude the abnormal leaking vessels and in the surrounding retina 1 week after her first vistit. T wo weeks later, additional photocoagulatioin was performed in the same lesion and then we found that all the abnormal vessels were covered with moderately white coagulums. Thereafter she was carefully followed and evaluated at 2-week to 3-month intervals. Fifteen months after first photocoagulation, we noticed all the retinal vascular lesioins were obiterated and replaced with the white glial tissue on the fundus examination and these findings were confirmed by fluorescein angiography, which disclosed complete obliteration of the abnormal vasculatures with little leakage, Final visual acuity of the left eye was 0.5.
