经瞳孔温热疗法 (transpupillary thermotherapy,TTT)是采用 810 nm波长二极管激光通过散大的瞳孔对眼底病灶进行加热的治疗方法 ,在临床上应用不过才几年时间 ,却在脉络膜黑色素瘤、脉络膜血管瘤、视网膜母细胞瘤、老年性黄斑变性的治疗中取得了较好的疗效 ,并具有非侵入性和较少并发症的优点 ,但还有待进一步的研究并验证和发展 Transpupillary thermotherapy (TTT) is a method of heating a fundus with a 810 nm wavelength diode laser through a dilated pupil. However, it has only been used for several years in clinical practice, but has been used in choroidal melanoma, choroidal blood vessels Neoplasms, retinoblastoma, and age-related macular degeneration, and has the advantages of noninvasiveness and less complications, but further study and verification and development are needed
