PURPOSE:: The purpose of this study was to report the efficacy of topical cyclosporine 0.05% at a frequency of 3 to 4 times daily in severe dry eye disease.
METHODS:: We retrospectively identified a cohort of patients with severe dry eye disease who had shown inadequate response to at least a 4-month course of treatment with twice-daily use of topical cyclosporine 0.05% but who showed significant improvement to more frequent dosing.
RESULTS:: Twenty-two patients, including 13 patients with ocular graft-versus-host disease and 9 patients with primary or secondary Sjögren's syndrome, were included. After a minimum of a 2-month course of treatment with more frequent dosing of cyclosporine 0.05% (3 times a day in 7 patients and 4 times a day in 15 patients), overall dry eye symptoms were improved in 15 (68.2%) patients (9 patients with ocular graft-versus-host disease and 6 patients with Sjögren's syndrome). Mean corneal fluorescein staining scores (National Eye Institute scale of 0-15) improved (decreased) from the baseline (precyclosporine use) by -3.5 (range, 0 to -7) in patients with ocular graft-versus-host disease (P < / = 0.0008) and -2.8 (range, 0 to -5) in patients with Sjögren's syndrome (P < / = 0.001). After treatment with high-frequency use of cyclosporine 0.05%, the global physician assessment of dry eye status was favorable (improved) in 16 (72.7%) patients. Three (13.6%) patients reported new-onset symptoms of burning or irritation with the use of high-frequency dosing of topical cyclosporine. No other associated adverse effect was reported.
CONCLUSION:: These data suggest that patients with severe dry eye may require more frequent dosing of topical cyclosporine 0.05% than twice daily.
