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).
