Corneal surface temperature decreases with age

Abstract

Infrared temperature measurement has found numerous applications in the detection and diagnosis of ocular and systemic disease. In the study of ocular temperature it is important to consider all parameters which might influence recorded measurements. Examples of such parameters include room temperature, time of day and age of subject. This communication discusses the effect of age on ocular temperatures measured with a modern, wide field, colour-coded infrared detector. It is demonstrated that ocular surface temperature decreases by -0.010 degrees C per year throughout life, although the rate of change increases after middle age.
