Abstract

Purpose: This study aimed to evaluate whether the digital eye strain (DES) was associated with the low central corneal thickness (CCT).

Methods: This observational cross-sectional pilot study was conducted from April 2023 to October 2023 at a tertiary eye care centre in North India, where CCT values were compared between subjects with DES and those without DES. Two hundred and eighty subjects (n = 280) aged 15-40 years with clear corneas and lenses were initially included in this study. Those with corneal opacity, corneal degeneration, pregnancy, and diabetes were excluded. These subjects were then assessed with a 'computer vision syndrome questionnaire (CVS-Q)' test. Participants having a score ≥ 6 were grouped as the "DES group" and participants having a score < 6 were grouped as the "Control group". The participants from each group were then examined with Spectral Domain Ocular Coherence Tomography (SD-OCT) to measure CCT. The primary outcome was to evaluate the comparative difference in CCT values between the two groups as well as the association of DES with CCT values.

Results: The study included one hundred and forty (n = 140) subjects each in the DES group and the control group. The DES score assessed with the CVS-Q questionnaire ranged from 6 to 32 in the DES group, with a mean ± SD of 17.08 ± 7.01. The overall mean CCT was 507.31 ± 31.01 (median, 512 microns; range, 450-601 microns). There was a significant difference in the mean CCT between the two groups, with lower mean CCT values in the DES group (487.76 ± 23.61 microns) than the control group (526.87 ± 24.53 microns) (p < 0.0001). The CVS-Q test score had moderate inverse correlation in the DES group (Pearson's r = - 0.42, p < 0.01) and negligible correlation (Pearson's r = - 0.14, p = 0.12) in the control group with CCT.

Conclusion: Central corneal thickness was observed to be reduced among the subjects with digital eye strain (DES).

数码眼疲劳与中央角膜厚度的关系：一项横断面观察性初步研究。

目的：本研究旨在评估数字眼疲劳（DES）是否与低中央角膜厚度（CCT）相关。方法：这项观察性横断面试点研究于2023年4月至2023年10月在印度北部的一家三级眼科保健中心进行，比较了DES患者和非DES患者的CCT值。280名年龄在15-40岁、角膜和晶状体透明的受试者（n = 280）最初被纳入这项研究。排除有角膜混浊、角膜变性、妊娠和糖尿病的患者。然后用“计算机视觉综合征问卷（CVS-Q）”测试对这些受试者进行评估。评分≥6分的受试者分为DES组和评分为a分的受试者。结果：DES组和对照组各纳入140例受试者。采用CVS-Q问卷对DES组进行评分，评分范围为6 ~ 32分，平均±SD为17.08±7.01。总平均CCT为507.31±31.01(中位数，512微米；范围，450-601微米)。两组间的平均CCT差异有统计学意义，DES组的平均CCT值（487.76±23.61 μ m）低于对照组（526.87±24.53 μ m） (p结论：数字眼疲劳（DES）患者角膜中央厚度减少。
