ABSTRACT
The role of temperature measurement in the human body has been described since 400 BC by the Greek physician Hippocrates. Heat emission, as a by-product of tissue metabolism, is transferred to the body surface by conduction, convection, through the human vascular system [1]. The measurement of ocular surface temperature (OST) to aid the understanding of ocular physiology has been widely reported in the literature since the 1960s [2-8].
