Temperature distributions in porcine orbital tissues following the use of CO2 and Nd:YAG lasers

M K Chedid et al. Ophthalmic Surg. 1993 Feb.

Abstract

Temperature distributions in the orbital tissues of a live porcine model were obtained during and immediately following the application of CO2 and Nd:YAG (both contact and noncontact) laser irradiation to muscle tissue adjacent to the optic nerve. Temperatures were measured with thermocouples and an infrared-sensitive thermographic camera system. Significant thermal spread was observed only in the case of the contact Nd:YAG laser, along with histologic evidence of damage to the optic nerve. After the laser was switched off, the target cooled with a time constant on the order of 10 seconds.
