Background: The aim of this study was to evaluate the prevalence of long-term recurrence after topical nonpreserved methylprednisolone pulse therapy for the treatment of keratoconjunctivitis sicca (KCS) with Sjögren's syndrome. Methods: A total of 106 eyes of 53 Sjögren's syndrome patients were included in the study. All patients were treated with topical nonpreserved 1% methylprednisolone solution. Initial therapy consisted of eyedrops 4 times a day for 2 weeks, and then patients were reevaluated and tapered off the medication every 2 weeks until discontinuation. Tear film breakup time (TBUT), Schirmer test, corneal fluorescein staining, and subjective symptom scores were measured. Additionally, impression cytology of the bulbar conjunctiva was performed. The overall success rates and success period were determined using the Kaplan-Meier survival curve. Results: A reduction in subjective symptoms and fluorescein staining, and an improvement in TBUT and Schirmer test results, was observed after treatment (PF < 0.001). Impression cytology specimens revealed a significantly increased number of periodic acid-Schiff-positive cells after treatment. After the first pulse therapy, mean survival was 56.6 weeks and 11 (20.8%) patients recurred. After the second pulse therapy, mean survival was 72.4 weeks and only 1 patient recurred. No serious complications, including intraocular pressure elevation and cataract formation, were encountered during the entire follow-up period. Conclusions: Topical nonpreserved methylprednisolone pulse therapy proved to be a safe, effective long-term treatment of improving subjective and objective dry eye factors in KCS patients with Sjögren's syndrome.
