Abstract
Purpose: To analysis of the multifocal electroretinogram outcomes of computer vision syndrome (CVS). Methods: In this observational cross-sectional case-control study, 59 students were grouped into CVS-diagnosed (n=36 eyes) and control (n=23 eyes). All completed the CVS-Q questionnaire and had mfERG testing to evaluate foveal function. Results: We documented statistically significant reduction in foveal responses in CVS versus control groups in mean mfERG Rings 1 and 2 with Quadrants 2 (P=<0.002, 0.02 and 0.01, respectively. Conclusion: This study documented the screen-induced foveal dysfunction that associates CVS using mfERG examination which revealed significant reduction in foveal responses in CVS group versus control group. Clinical Trials Registration: ClinicalTrials.gov (ID: NCT06106347).
