Topical rebamipide improves the ocular surface in mild lagophthalmos.

Administration of topical rebamipide improves the ocular surface in dry eye. We consecutively studied seven eyes in seven cases (three males and four females) with mild lagophthalmos (three cases after eyelid surgery, two cases of incomplete facial nerve palsy, and two cases of senile ectropion) during the treatment of corneal disorders with rebamipide eye drops four times daily for 2 weeks. The fluorescein corneal staining (FCS) score, tear film break-up time (TBUT), Schirmer's test, and decimal visual acuity were examined. Ocular symptoms were examined and scored by questioning each patient before and after administration of the drug. In all seven eyes, inferior corneal erosion decreased or disappeared within 2 weeks after administration of topical rebamipide. The FCS score was significantly improved (P < 0.05). The TBUT was significantly extended from 2.9 ± 0.5 seconds to 5.2 ± 0.4 seconds (P < 0.05). The scores of ocular symptoms, such as eye pain, dryness, blurred vision, and foreign body sensations, were significantly improved (P < 0.05).Topical rebamipide was effective for corneal disorders in mild lagophthalmos. This drug may provide a novel approach to treat lagophthalmos.
