This study aimed to evaluate whether the digital eye strain (DES) was associated with the low central corneal thickness (CCT).
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.
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.
Central corneal thickness was observed to be reduced among the subjects with digital eye strain (DES).
本研究旨在评估数码眼疲劳（DES）是否与中央角膜厚度（CCT）降低有关。
本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护理中心进行，比较了患有DES的受试者和未患有DES的受试者的CCT值。最初纳入了280名年龄在15至40岁、角膜和晶状体清晰的受试者。排除了患有角膜混浊、角膜变性、妊娠和糖尿病的受试者。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。得分≥6分的参与者被归为“DES组”，得分<6分的参与者被归为“对照组”。然后用光谱域光学相干断层扫描（SD-OCT）对每组参与者进行检查以测量CCT。主要结果是评估两组之间CCT值的比较差异以及DES与CCT值的关联。
DES组和对照组各有140名受试者。DES组用CVS-Q问卷评估的DES得分范围为6至32分，平均±标准差为17.08±7.01。总体平均CCT为507.31±31.01（中位数，512微米；范围为450至601微米）。两组之间的平均CCT存在显著差异，DES组的平均CCT值（487.76±23.61微米）低于对照组（526.87±24.53微米）（p<0.0001）。在DES组中，CVS-Q测试得分与CCT呈中度负相关（Pearson相关系数r=-0.42，p<0.01），而在对照组中相关性可忽略不计（Pearson相关系数r=-0.14，p=0.12）。
