Abstract

Purpose: The utilization of clinical videography technique in the assessment of dynamic tear meniscus was not explained thoroughly. This study was conducted to assess the rising speed of tear meniscus using clinical videography technique. Method: This cross-sectional study recruited 342 subjects with 642 eyes. Dry eye was indicated if the tear film break-up time was less than 5 seconds and schirmer test with anaesthesia values was less than 5mm/5 minutes The meniscus rising speed was recorded using slit lamp videographer. The tear meniscus rising speeds were measured at 1 (TMRS 1), 2, (TMRS 2), 3 (TMRS 3), 4 (TMRS 4), 5 (TMRS 5) seconds after opening the eye without blinking. Results: 83 eyes were classified in the dry eye group (DEG) while the remaining 559 eyes in non-dry eye group (NDEG) The mean of TMRS at one second (TMRS 1) was 0.44 ± 0.24 mm/second, reduces after holding the blinking for 5 seconds (TMRS 5 = 0.09 ± 0.24 mm/second). There were significant differences between non-dry eye and dry eye groups in TMRS 1, TMRS 2, and TMRS 3 (p < 0.05), but not for TMRS 4 and TMRS 5 (p > 0.05). The rising speeds after 3 seconds of holding blinking was found significantly lower in dry eye group than in non-dry eye. Conclusion: The clinical videography technique can be utilized objectively to assess the tear meniscus rising speed. There is a direct correlation between tear meniscus rising time and dry eye status.
