Abstract:
A sensitive thermometer utilizing thermistor as a sensing element has been constructed in order to measure the temperatures in various ocular tissues. The Wheatstone bridge was used to detect the changes in thermistor resistance. The out-put of the bridge was fed into a single-stage differential DC amplifier and read by an micro-ammeter. There was a linear relationship between temperature and meter scale. The thermistor was inserted into the inferior conjunctival sacs of 158 healthy normal human eyes. The average temperature was found to be 35.14 +/- 1.08 (in C). No difference due to sex and age distribution was found to exists. Preliminary temperature measurement has been done on rabbits. Their results are shown graphically in Fig. 3.
