Abstract
Ocular temperature distribution is important for both laboratory and clinical investigations. Environmental conditions of air movement, temperature, humidity, and thermal radiation influence the temperature distribution in the eye. We have studied some of these factors by determining the effects of ambient temperature and wind velocity on the corneal surface temperature. We also measured intracorneal temperature directly. The results, which indicate that a small thermal gradient is present across the cornea, are compatible with heat-transfer calculations. Air current exerts an important influence on anterior corneal temperature.
