단순포진각막염 환자에서 예방적 항바이러스제의 투여 후 장기 관찰 결과

Abstract

Purpose: We analyzed the effectiveness of prophylactic oral antivirals in preventing herpes simplex keratitis (HSK) and the clinical manifestations of recurrence. Methods: A retrospective analysis was conducted on 30 eyes of 30 patients diagnosed with HSK who received prophylactic oral antiviral agents for > 6 months. We analyzed the initial and recurrent clinical features of HSK, the recurrence rate, and the relationship between recurrence and the duration of oral antivirals. Results: The mean age of the patients was 64.5 ± 14.0 years, and the mean follow-up duration was 72.4 ± 40.3 months. Of the 30 eyes, 21 (70%) experienced HSK recurrence. The initial clinical features of recurrent cases included herpetic epithelial keratitis (14.3%), stromal keratitis (47.6%), and endotheliitis (38.1%). Notably, no significant associations were observed between the initial clinical features of HSK or the duration of oral antivirals and HSK recurrence. However, male patients exhibited a significantly higher recurrence rate. Epithelial keratitis (47.6%) was the most common HSK type observed during recurrence. Conclusions: A recurrence rate of 70% was observed in patients who received prophylactic oral antiviral treatment for > 6 months. Herpetic epithelial keratitis was the most common clinical phenotype after recurrence. Notably, long-term clinical monitoring could assist in predicting and preventing recurrence. © 2024 Korean Ophthalmological Society (KOS). All rights reserved.
