Static and Dynamic Measurement of Ocular Surface Temperature in Dry Eyes

Figure 3

(Dynamic measures) graphs showing the mean change OST (relative to baseline) during the 10 s sustained eye opening: (a) GCC and MOST; (b) and ; (c) T1; (d) T4; (e) CT and LT; (f) CN and LN in (solid circles) dry eye subjects and (open circles) controls. Values in boxes represent the cooling rate and net change in OST over the 10 s period in dry eye and control groups, respectively. A comparison of mean at each 1 s interval was performed using unpaired -test, . A typical standard deviation for GCC was ±0.29 (= average std deviation) for dry eye and ±0.30 for controls and for MOST it was ±0.15 for dry eye and ±0.18 for controls. A typical standard deviation for was ±0.33 for dry eye and ±0.32 for controls and for it was ±0.11 for dry eye and ±0.13 for controls. A typical standard deviation for T1 was ±0.14 for dry eye and ±0.11 for controls and for T4 it was ±0.21 for dry eye and ±0.16 for controls. A typical standard deviation for CT was ±0.19 for dry eye and ±0.17 for controls and for LT it was ±0.23 for dry eye and ±0.29 for controls. A typical standard deviation for CN was ±0.14 for dry eye and ±0.16 for controls and for LN it was ±0.22 for dry eye and ±0.23 for controls.
