Abstract

Purpose : Blepharoptosis refers to inferodisplacement of the upper eyelid. It is one of the most common eyelid disorders occurring in about 12% of adults over age 50. It may cause significant superior visual field impairment as the upper eyelid margin obstructs the superior visual field. Treatment is surgical and targets 1 of 2 upper eyelid retractor muscles: the levator muscle and Müller’s muscle. Müller’s muscle is innervated by adrenergic fibers from the cervical sympathetic chain. The active ingredient of RVL-1201 (oxymetazoline 0.1%) is an α1 and partial α2 adrenergic agonist capable of contracting Müller’s muscle through direct transconjunctival contact of this sympathomimetic agent. The result is upper eyelid elevation.

Methods : 140 subjects in a Phase 3, randomized, multicenter, double-masked, placebo-controlled study were randomized in a 2:1 ratio into 1 of 2 treatment arms and treated with RVL-1201 or placebo (vehicle) once daily for 6 weeks. Blepharoptosis was defined as lid marginal (light) reflex distance (MRD) ≤ 2.5mm and a superior visual field loss of ≥8 points out of the top 2 rows of a possible 17 points using a Leicester Peripheral Field Test (LPFT) program on the Humphrey Visual Field analyzer. Four rows (35 points) exist at or above 10° from fixation in the superior visual field. Dosing once every morning, Group 1 (N = 95) took one drop of RVL-1201 per eye and Group 2 (N = 45) took one drop of vehicle per eye. The study eye was used in the analysis of efficacy.

Results : The number of LPFT points seen was significantly increased in RVL-1201 group vs the vehicle group compared to baseline at both primary efficacy time points (values shown are mean difference between groups, P-value, 95% confidence limits): Day 1 Hour 6 (3.68, P < 0.0001, 2.00, 5.36) and Day 14 Hour 2 (4.41, P < 0.0001, 2.52, 6.31). Significant increases in MRD were also found between the RVL-1201 and vehicle groups compared to baseline at both primary efficacy time points. RVL-1201 was well tolerated; the adverse event profile was similar between the RVL-1201 and vehicle groups.

Conclusions : These results support the hypothesis that once daily RVL-1201 Ophthalmic Solution significantly improves the superior visual field by increasing the number of points seen when compared to vehicle and elevates a ptotic upper eyelid. This product could serve as an alternative nonsurgical treatment for upper eyelid ptosis.
