Transscleral thermotherapy: short- and long-term effects of transscleral conductive heating in rabbit eyes.

OBJECTIVE To determine the highest safe treatment temperature, at 30- and 60-second exposure durations, for transscleral thermotherapy (TSTT) of choroidal melanoma. METHODS AND DESIGN Transscleral conductive heating was performed in 15 rabbits at 50 degrees C to 70 degrees C for 30 or 60 seconds. The thermal lesions in the ocular fundus were monitored for 4 months with ophthalmoscopic, photog...
