| Summary: | Introduction: Schirmer test is mainly used for measuring tear production. The purpose of this study is to assess the production of tears using ocular surface imaging.
Materials and Method: 321 subjects with 642 eyes were involved in this cross-sectional study with convenient sampling. Schirmer test with anaesthesia (STA) and slit lamp videography were conducted. The parameters obtained from slit lamp videography were 30-seconds blinking rate, tear film break-up time (TFBUT), lipid floating time (LFT), and tear meniscus height (TMH).
Results: STA was significantly correlated with 30-seconds blinking rate (r = 0.12, p < 0.05), TFBUT (r = 0.25, p < 0.001), and TMH (r = 0.10, p < 0.05). However, the relationship between STA and LFT was not significant (p > 0.05).
Conclusion: The parameters of 30-seconds blinking rate, TFBUT and TMH in ocular surface imaging are indirect indication for the assessment of tear production.
