Abstract
Purpose :
To assess the effect of a 6-month course of cyclosporine 0.05% ophthalmic emulsion (Restasis®, Allergan, Inc.) on ocular surface staining, visual function, and other measures of dry eye (DE) in subjects who experience discomfort while engaging in electronic visual tasking.
Methods :
In this multi-center, open-label, 5-visit study, DE patients administered Restasis® twice-daily for 6 months. Patients were included in the study if they were 18 to 55 years of age, had a history of DE, used electronic devices (computers, tablets, phones) on a daily basis, had a score of 2 or greater on the Ora Calibra™ Ocular Discomfort and 4-Symptom Questionnaire, an Ocular Surface Disease Index (OSDI) score >12, and presence of corneal staining at visit 1. Primary efficacy endpoints were ocular surface staining, and visual performance at 6 months.
Results :
Fifty one subjects were enrolled in the study; 46 subjects completed the study and were considered per protocol. Forty-one subjects were female (82%); mean subject age was 46.3±8.30. At 6 months, statistically significant reductions in all regional fluorescein staining was observed; in particular, central corneal staining was reduced by -0.75±0.66 (p<0.0001). Subjects also reported statistically significant improvements in visual function as measured by the OSDI questions for blurred vision (p<0.0001), poor vision (p=0.0002), driving at night (p=0.016), working with a computer (p<0.0001), and watching television (p<0.0001). Among secondary endpoints, Schirmer’s scores for all subjects was increased by 4.0±7.13 mm (p=0.0004), with 32% of all subjects increasing by at least 5 mm, and 16% increasing by at least 10 mm.
Conclusions :
Restasis® improves ocular surface staining and patient reported visual function in patients who engage in electronic visual tasks after 6 months of dosing.
