Abstract

Objectives: To investigate the lower lid margin thickness (LLMT) from the posterior lash line to the anterior edge of tear meniscus with Oculus Keratograph 4 (K4).

Methods: This was a prospective, single-center, observational study. A total of 90 volunteers aged 18 to 79 years with no ocular diseases were included in this study. The LLMT of 90 subjects was measured twice by the same person with K4. To determine the reliability of K4, measuring the LLMT of 30 normal subjects was separately performed by two operators.

Results: The LLMT measurements with K4 between two operators demonstrated a good reproducibility (0.94±0.18 vs. 0.96±0.16 mm; intraclass correlation coefficient=0.88; P=0.18). The mean age of 90 volunteers (42 men and 48 women) was 45.5±14.1 years. The LLMT was 0.95±0.17 mm, which was a significant positive correlation with age (rs=0.57; P<0.001). In addition, there was no significant difference in the LLMT between genders (0.97±0.16 vs. 0.93±0.18 mm; P=0.32).

Conclusions: We found that K4 was a reliable tool in the LLMT measurements, and the LLMT seemed to be closely related to age but not to gender.

眼内角膜造影术测量下睑缘厚度。

目的:应用4号眼角膜摄影仪(K4)观察眼睑下缘厚度(LLMT)。方法:这是一项前瞻性、单中心观察性研究。本研究共纳入90名年龄在18至79岁之间、无眼部疾病的志愿者。90名受试者的LLMT由同一名K4患者进行两次测量。为了确定K4的可靠性，由两名操作员分别测量30名正常受试者的LLMT。结果:两名操作人员使用K4测量LLMT的重现性良好(0.94±0.18 vs 0.96±0.16 mm;类内相关系数=0.88;P = 0.18)。90名志愿者(男42名，女48名)的平均年龄为45.5±14.1岁。LLMT为0.95±0.17 mm，与年龄呈显著正相关(rs=0.57;结论:我们发现K4是LLMT测量的可靠工具，LLMT似乎与年龄密切相关，而与性别无关。
