Abstract

Purpose

To explore effects of topical 1 % selenium sulfide on signs and symptoms in symptomatic contact lens-wearers, in an exploratory 4-month prospective placebo-controlled double-masked randomised trial.

Methods

Symptomatic wearers (Contact Lens Dry Eye Questionnaire-8 [CLDEQ-8] score>12) with meibomian gland dysfunction (meibomian gland score (MGS)≤12), were enrolled and received either active (AZR-MD-001-containing 1 % selenium sulfide), or vehicle ointment, to the lower eyelid margin twice-weekly. MGS, meibomian glands-yielding liquid secretion (MGYLS), lipid layer thickness, tear meniscus height, tear break-up time, tear evaporation rate, lid wiper epitheliopathy, CLDEQ-8 and comfortable wear time (CWT) were measured at baseline and to 4-months. Differences between active and placebo were compared to baseline.

Results

Fourteen participants (5M:9 F, 30.8 ± 13.8 years) completed the study. In the active group, change in MGS from baseline improved by 1-month (mean difference 7.9 ± 8.0, p = 0.03), to 4-months (16.0 ± 11.3, p < 0.01). MGYLS improved from baseline by 1.5-months (4.0 ± 3.3) to 4-months (4.1 ± 4.3, p < 0.01). In the vehicle, change in MGS (12.1 ± 10.7) and MGYLS (3.9 ± 3.2) were improved at 4-months only (p < 0.01). CLDEQ-8 score improved at 1-month and 4-months compared to baseline (−4.4 ± 3.2, −5.1 ± 4.7, p ≤ 0.02) in the active and at 4-months only in the vehicle group (−4.4 ± 6.4, p = 0.02). In the active group, CLDEQ-8 visual function scores improved at 1- and 4-months (p ≤ 0.02) and CWT at 4-months (median 7 vs.10 h, p = 0.025). Other signs were unchanged.

Conclusions

This exploratory study indicates that twice-weekly use of AZR-MD-001 ointment can rapidly improve gland patency and secretion in symptomatic contact lens-wearers. AZR-MD-001 reduced changeable/blurry vision and prolonged CWT, suggesting relevant future endpoints.

期刊介绍: The Ocular Surface, a quarterly, a peer-reviewed journal, is an authoritative resource that integrates and interprets major findings in diverse fields related to the ocular surface, including ophthalmology, optometry, genetics, molecular biology, pharmacology, immunology, infectious disease, and epidemiology. Its critical review articles cover the most current knowledge on medical and surgical management of ocular surface pathology, new understandings of ocular surface physiology, the meaning of recent discoveries on how the ocular surface responds to injury and disease, and updates on drug and device development. The journal also publishes select original research reports and articles describing cutting-edge techniques and technology in the field. Benefits to authors We also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.
