Tear Meniscus Evaluation by Anterior Segment Swept-Source Optical Coherence Tomography

Purpose: To investigate the repeatability of tear meniscus measurements using anterior segment swept-source optical coherence tomography (OCT) and the relationship of tear meniscus measurements with tear film breakup time and Schirmer test results.Design: Prospective, observational, cross-sectional study.Methods: We enrolled 26 healthy subjects (26 eyes; 20 men and 6 women; mean age, 36.5 ± 6.8 years) at the University of Tokyo School of Medicine, Tokyo, Japan, in this study. Examinations were conducted in the following sequence: anterior segment vertical raster scans by swept-source OCT, tear film breakup time, and Schirmer test. Each subject underwent OCT measurements twice by the same grader, (Read more...)
