Abstract/OtherAbstract:
Purpose. To show the diurnal variation of tear osmolarity in normal subjects. Methods. Thirty volunteers were recruited. Tear osmolarity was measured with TearLab osmolarity system at 3-hour regular intervals between 8:00 am and 5:00 pm. One-way analysis of variance test was used for statistical analysis. Results. Thirty healthy volunteers (all men) with a mean age of 29.6±4.3 years (range 18-45) were recruited. The difference between measurements at 8:00 am and 11:00 am, 8:00 am and 2:00 pm, 8:00 am and 5:00 pm, 11:00 am and 2:00 pm, 11:00 am and 5:00 pm, and 2:00 pm and 5:00 pm were not statistically significant (one-way analysis of variance test, p>0.05). Conclusions. In normal subjects, tear osmolarity seems to have a stable profile during the daytime.
