%X OBJECTIVE: To examine the frequency of recurrences, risk factors, and long-term clinical outcomes in subjects with herpes zoster ophthalmicus (HZO).
METHODS: Retrospective cohort study.
METHODS: All subjects with acute HZO seen at a single center from 2006 to 2016 were included in the study. The primary outcome measure was eye disease recurrence. The secondary outcome measure was moderate vision loss (≤20/50).
RESULTS: A total of 869 patients with acute HZO were identified, with a median follow-up time of 6.3 years (interquartile range 3.7-8.9 years). In all, 551 recurrences were observed, and at least 1 recurrence was seen in 200 subjects (23.0%), with uveitis (34.8%) being the most common. The median time to first recurrence was 3.5 months. Predictors of disease recurrence included immunosuppression (P = .026), higher presenting intraocular pressure (P = .001), corneal involvement (P = .001), and uveitis (P < .001) on multivariate analysis. Topical steroids were initiated in the first month of presentation in 437 subjects, and recurrence was observed in 184 (42.1%) of these subjects. Following cessation of topical steroid treatment, recurrence occurred after a median of 1.4 months (90% within 7 months). Moderate vision loss (≤20/50) occurred in 15.5%, 28.6%, 31.4%, 50.0%, and 57.4% of eyes with 0, 1, 2, 3, and 4 or more recurrences.
CONCLUSIONS: Recurrence of HZO eye disease is common, with an increased risk of vision loss with more recurrences. These findings indicate the need for close monitoring for potential recurrences, especially after cessation of topical steroid treatment, and in individuals with identified risk factors for recurrence.
