Abstract:
Objective To investigate the impact factors for temperature of cornea(TOC) and analyse the relationship between TOC and evaporative dry eye. Methods Two hundred and fifty-seven patients(405 eyes) with normal lacrimal secretion received dry eye tests.Patients were divided into positive group and negative group according to the results,and were randomly subdivided into 4 groups with different environment temperature(T) and relative humidity(RH).For all eyes,TOC,body surface temperature(TBS) of forehead and center corneal thickness(CCT) were measured right after blinking.The impact factors for TOC and the differences in TOC between positive group and negative group were analysed.Results TOC was positively correlated with TBS(r=0.89),T(r=0.75) and RH(r=0.60)(P
