Comparison of Efficacy of Two Different Topical 0.05% Cyclosporine A Formulations in the Treatment of Adenoviral Keratoconjunctivitis-Related Subepithelial Infiltrates

Subepithelial infiltrates secondary to adenoviral keratoconjunctivitis may persist for years and cause blurred vision, halos, glare, and photophobia. These infiltrates arise from immune reaction against the virus, and few studies have reported topical cyclosporine A to be effective in the treatment of subepithelial infiltrates. Herein, we describe a patient with adenoviral keratoconjunctivitis-related subepithelial infiltrates who did not respond to treatment with a new topical cyclosporine A emulsion prepared with castor oil (Depores 0.05%; Deva İlaç, Kocaeli, Turkey), while the FDA-approved nanoemulsion formulation provided improvement in symptoms and reduced the inflammatory reaction (Restasis 0.05%; Allergan, Irvine, Calif., USA).
