Abstract: Objective To observe the histopathological manifestations and the evolvement processes of different retinal reactions caused by transpupillary thermotherapy (TTT). Methods Transpupillary thermotherapy (TTT) was performed to the retina of normal rhesus monkey. The histopathologic changes of different laser spots no visible reaction, mild reaction and intense reaction at different time 1 d, 1 week, 2 week, and 1 month were observed. Results No change was found in no visible reaction laser spots by light microscope. The histopathologic changes of mild reaction were confined to the outer retina. The histopathologic changes of intense reaction involved the whole layer of retina. The histopathologic changes turned to stable after 2 weeks. Conclusion Different TTT reaction can result in the different extent damage to retina. Suitable reaction should be performed according to the nature of the diseases.
