title: [Regarding the method of the total tear production assessment].
abstract: Different Schirmer test I techniques presented in the literature have been reviewed and a comparative study of Schirmer test I results obtained with the eyes opened and closed has been conducted. The total tear production with the eyes opened vs. closed averaged 17.1+/-1.1 mm and 12-1.2 correspondingly (p=0.001; Mann-Whitney U test). In 22% of patients values were higher with the eyes closed rather than opened. The authors recommend to specify the conditions of the performed test when entering the results into the patient's chart.
