a What does TTT stand for? Answer Transpupillary Termo-Therapy How is TTT performed and what is the mechanism? Answer It utilizes diode laser with a wavelength of 810 nm. The spot size should cover the entire lesion for 60 sec. There should be no retinal changes observed during the treatment otherwise the laser should be stopped. The mechanisms of action is not completely understood. The laser penetrates the retina pigment epithelium and choroid with minimal effect on neurosensory retina and there is an estimated elevation of temperature of 10 degrees C. The possible mechanisms include vascular thrombosis and thermal inhibition of angiogenesis. End of viva 3
