Abstract：Objective To compare the test results of SchirmerⅠtest and ocular surface analyzer, evaluating two methods for diagnosis in dry eye.Methods Symptoms of 36 patients (72 eyes) were asked in turn, 36 cases of dry eyes (72 eyes) were esti-mated by ocular surface analyzer and SchirmerⅠtest.The correlations of measuring outcomes of ocular surface analyzer and SchirmerⅠtest were analyzed with Spearman’ s rank correlation analysis on both sides.Results Among those 10 patients who tested by Schirmer I test with wet lengths less than 5 mm/5 min, 9 were greater than grade 2.Among the 62 eyes, of which the wet lengths tested by SchirmerⅠtest were more than 5 mm/5 min, 40 eyes were in grades 2, 3, 4 and 5.23 eyes were in grades 2 with dry eye symptoms apparently.Spearman’ s rank correlation analysis showed that patients with higher dry eye grades, the wet length of SchirmerⅠtest was shorter on the contrary.It showed a negative correlation (rS =-0.314,P<0.05).Conclusions Both ocular surface analyzer and SchirmerⅠtest can diagnose dry eye from a different view, and reflect the severity of dry eye objectively.But ocular surface analyzer has more examination index, and its operation without trauma, its repeatability is strong.Ocular surface analyzer is an effective clinical method to diagnose dry eye.
