The Effect of Rebamipide on Ocular Surface Disorders Induced by Latanoprost and Timolol in Glaucoma Patients

Abstract EN

Purpose.

To examine the efficacy of ophthalmic rebamipide suspensions on ocular surface disorders induced by antiglaucoma eye drops.

Patients and Methods.

Forty eyes of 40 patients receiving latanoprost (0.005%) and timolol (0.5%) were included in this randomized prospective study.

The patients were randomly divided into two groups (n = 20): the rebamipide-treated group and controlgroup.

Changes in intraocular pressure, tear film break-up time (TBUT), and corneal epithelial barrier function were evaluated at baseline, 4 weeks, and 8 weeks after rebamipide administration.

Furthermore, superficial punctate keratopathy severity was evaluated by scoring the lesion area and density.

Results.

There was no significant difference in intraocular pressure before and after rebamipide treatment.

However, corneal epithelial barrier function improved significantly 4 and 8 weeks after rebamipide treatment.

TBUT was partially, but significantly, increased (P = 0.02) 8 weeks after rebamipide treatment, whereas no significant change was observed at 4 weeks.

Additionally, a significant decrease in area and density of keratopathy was observed 8 weeks after rebamipide treatment but not at 4 weeks.

The control group showed no significant difference compared to baseline.

Conclusions.

Our data suggests that rebamipide treatment may reduce the occurrence of drug-induced ocular surface disorder.
