Abstract
PURPOSE: To investigate the relationship between the radius of tear meniscus curvature (TMR) and tear meniscus height (TMH). METHODS: Twenty-nine eyes of dry-eye patients (all left eyes; two males, 27 females, aged 26 to 85 years [mean +/- SD; 60 +/- 14.4]) were enrolled in the study. TMR was measured at the tear meniscus of the central lower lid with a newly developed videomeniscometer. At the same region of the eye, TMHs were measured without fluorescein (TMH-M) and after 5 minutes with fluorescein (TMH-MF), using a slit lamp equipped with a micrometer. TMHs were also measured on cross-sectional photographs of the fluorescein-stained meniscus (TMH-P). RESULTS: The values of TMR, TMH-M, TMH-MF, and TMH-P (mean +/- SD, mm) were 0.22 +/- 0.09, 0.19 +/- 0.09, 0.21 +/- 0.14, and 0.24 +/- 0.09, respectively. There was significant correlation between TMR and TMH-M, TMH-MF, and TMH-P values (TMR versus TMH-M: r = 0.596, p = 0.0005; TMR versus TMH-MF: r = 0.587, p = 0.0006; TMR versus TMH-P: r = 0.605, p = 0.0003). CONCLUSION: There is a significant correlation between TMR and TMH. Videomeniscometry has some merits over conventional methods for obtaining tear meniscus parameters.
