经瞳孔温热疗法 (transpupillary therm otherapy,TTT)采用 810 nm激光 ,治疗后极部多种体积较小的脉络膜视网膜肿瘤。近年来 ,人们摒弃了治疗时视网膜上需产生不同程度可见光斑的传统光凝治疗观念 ,TTT试图以不产生可见反应或仅见轻微颜色反应来治疗脉络膜新生血管膜。本文综述了此方面的研究进展 Transpupillary thermotherapy (TTT) using 810 nm laser, after the treatment of a variety of smaller polyps of the chorioretinal tumors. In recent years, people abandon the traditional treatment of retinal need to produce varying degrees of visible light phototherapy concept of treatment, TTT tried to produce no visible reaction or only a slight color reaction to treat choroidal neovascular membrane. This article summarizes the research progress in this aspect
