Clinical Efficacy of 2% Rebamipide in Patients With Video Display Terminal-Associated Dry Eye Disease: A Prospective, Randomized, Double-Blinded Study.

Purpose: To compare the effects of 2% rebamipide clear solution and 0.1% sodium hyaluronate eye drops in patients with visual display terminal (VDT)-related dry eye disease (DED).

Design: Prospective, randomized, double-blinded Study.

Methods: This was a prospective, double-blind, and randomized controlled study. Patients with VDT-related DED were randomly allocated to a 2% rebamipide (REB) group or a 0.1% sodium hyaluronate (HYA) group (4 times/day for 4 weeks). The ocular surface disease index (OSDI), dry eye questionnaire-5 (DEQ-5), Placido disk-tear film analyzer, fluorescein-stained tear break-up time (FBUT), ocular surface staining score, and Schirmer 1 test were examined before and after the instillation of drug.

Results: A total of 56 eyes of 28 patients (28 eyes of 14 patients in each group) were included. There were no significant differences in the baseline data. The OSDI, DEQ-5, FBUT, and conjunctival erosion scores improved significantly in both groups after treatment. In the REB group, corneal staining and bulbar nasal redness scores also improved significantly after treatment ( P <0.001 and 0.036, respectively), whereas no significant differences were found in these parameters in the HYA group ( P =0.326 and 0.118, respectively). The REB group showed a significantly larger decrease in the corneal staining score than the HYA group ( P =0.016). No adverse reactions were observed.

Conclusions: A 2% rebamipide clear solution effectively improved the symptoms and signs in patients with VDT-related DED and was superior to 0.1% sodium hyaluronate ophthalmic solution in improving corneal epithelial damage, making it a safe and effective treatment option for VDT-related DED.
