Threshold Lesion Temperatures in Laser-Irradiated Rabbit Eyes.

摘要

The purpose of this research was to measure threshold temperatures corresponding to the formation of minimum ophthalmoscopically visible lesions induced in rabbit fundi by a ten-second exposure from an argon C. W. laser (4880A). The posterior pole of the eye was surgically exposed and a specially designed microthermocouple with a 20-micron diameter tip was inserted into the ocular fundus to measure temperature rises. The mean threshold temperature for 30 measurements in 13 rabbits was 54C. System error was estimated at 5% of temperature rise, or slightly less than 1C.
