Abstract Purpose: To evaluate the impact of loteprednol 0.5% as initiation therapy, followed by topical cyclosporine (tCSA) maintenance therapy in patients with dry eye disease (DED). Methods: 121 patients with DED were enrolled in a multicenter, randomized, controlled, masked, prospective clinical trial. Patients received either initial loteprednol 0.5% or artificial tears for 2 weeks prior to starting maintenance tCSA therapy. Results: The loteprednol initiation group showed improved OSDI scores (p<0.01) at Day 14, decreased cyclosporine stinging at Day 30 (p<0.04), and improved corneal staining at Day 30 (p<0.05) compared to the placebo initiation group. Conclusion: Loteprednol initiation followed by tCSA maintenance improves patient compliance, reduces stinging and provides more rapid relief of dry eye disease than tCSA therapy alone. Introduction • Dry eye disease (DED) is an ocular surface disease that produces discomfort and irritation. • Cyclosporine ophthalmic emulsion 0.05% (Restasis®) is indicated to increase tear production in patients whose tear production is presumed to be suppressed due to ocular inflammation associated with keratoconjunctivitis sicca. However, the relief of dry eye signs and symptoms with cyclosporine therapy is often delayed by 1 to 6 months from the initiation of therapy, and 17% of patients experience burning and stinging leading to poor patient compliance.1 • Marsh & Pflugfelder2 showed that corticosteroid therapy in patients with DED improved signs and symptoms, improved tear clearance, and normalized mucus production, often having a sustained benefit after a 2 week pulse. In addition, corticosteroid treatment improved tear production by controlling inflammation and decreased the irritation associated with the use of cyclosporine by 75%.2,3 • Loteprednol etabonate ophthalmic suspension 0.5% (Lotemax®) is indicated for the treatment of steroid responsive inflammatory conditions associated with the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe. Purpose • The purpose of this study was to evaluate the impact of loteprednol 0.5% as initiation therapy in patients with DED. Methods • A total of 121 patients with DED were enrolled in this multicenter, randomized, controlled, masked, prospective clinical trial. • Patients received either initial loteprednol 0.5% or artificial tears for two weeks (Day 1 to14) prior to starting maintenance tCSA therapy (Day 15 to 60). Additional use of artificial tears was allowed as needed. • Patients were evaluated by the Ocular Surface Disease Index (OSDI) for symptoms and underwent full ophthalmic examination including BCVA, biomicroscopy with fluorescein and lissamine green staining, applanation IOP and Schirmer’s test without anesthesia on days 14, 30 and 60. Results • • Both treatments decreased central corneal staining over 60 days (P<0.005). Loteprednol etabonate/tCSA was more effective than artificial tears/tCSA in reducing central corneal staining (P=0.003).
