Objective  lt;br gt;To evaluate the clinical effect of transpupillary thermotherapy (TTT) on circumscribed choroidal hemangioma (CCH). Methods  lt;br gt;The clinical data of 12 eyes of 12 patients with CCH treated with TTT were retrospectively analysed. Infrared diode laser Iridex, oculight SLX was used in TTT at 810 nm and power between 220 and 1000 mW with a beam diameter of 1.2 or 2.0 or 3.0 mm, with 1 to 2 minutes of exposure time. The visual acuity, subretinal fluid, complication ,thickness and hyperfluorescence of CCH were observed pre- and postoperatively in the treated eyes. The average period of follow-up was 10 months (6-16 months).  lt;br gt;  lt;br gt;Results  lt;br gt;Among the 8 eyes with peripheral retinal detachment in 12 cases of CCH the peripheral subretinal fluid was completely absorbed in 6 eyes, and partially absorbed in 2 eyes after TTT treatment. In 8 patients undergone ultrasonography, the mean value of tumor thickness went down by 21.75 % in 7 eyes. The resultant visual acuity after treatment was improved in 3 eyes, maintained no change in 7 eyes and reduced in 2 eye. The fundus fluorescein angiography in 10 eyes revealed a significant decrease of the leakage in tumor. Postoperative complication of TTT in the 12 eyes included retinal hemorrhage (5 eyes) and retinal fold (1 eye). Conclusion  lt;br gt;TTT is an effective treatment for CCH.  lt;br gt;  lt;br gt;(Chin J Ocul Fundus Dis, 2002, 18: 190-092)
