Ocular surface temperature.

摘要: A wide-field color-coded infra-red imaging device was applied to the measurement of i) temperature profile across ocular surface and ii) temporal stability central corneal temperature, on 21 subjects. The thermographs showed a pattern ellipsoidal isotherms (major axis horizontal) approximately concentric about apex (coldest point) which slightly inferior geometric center cornea (GCC). GCC had mean (+/- SD) 34.3 +/- 0.7 degrees C (range 32.8 35.4 C). Temperature increased towards periphery with limbus being 0.45 warmer than (p less 0.0001). Following blink, cooled at rate 0.033 0.024 C/s 0.0001) over first 15s. Subjects whose corneas more slowly following blink demonstrated greater capacity avoid blinking for prolonged period 0.05). This improved method measuring has important applications in modeling physiology pathology.
