ABSTRACT
PURPOSE:
To examine risk factors associated with cerebrovascular accident (CVA) following herpes zoster ophthalmicus (HZO).DESIGN:
Retrospective cohort study.METHODS:
Review of medical records of all patients with HZO seen at the department of Ophthalmology, Auckland District Health Board, New Zealand, between January 1, 2006, and December 31, 2016. The main outcome measure was cerebrovascular accident within 12 months of diagnosis.RESULTS:
A total of 869 patients diagnosed with HZO were included in the study. The median age at onset of HZO was 65.5 years (interquartile range [IQR] 52.9-75.4), and 52.5% (n=456) were male. Antiviral therapy was started in 765 participants (88.0%), not used in 95 (10.9%), and not documented in 9 participants (1.0%). Four hundred sixty-eight participants (54.9%) received prompt oral antiviral therapy (≤72 hours of rash onset). A CVA occurred in the 12 months following HZO in 14 patients (1.6%) and was most common in older patients, occurring in 2.5% aged ≥65 years, 0.7% aged 40-65 years, and 0.9% aged <40 years. Hazard of CVA was highest immediately following HZO, with median time to CVA of 2.3 months (IQR 0.8-5.9 months). Patients who received prompt acyclovir had a 76.2% lower hazard of CVA (0.9% vs 2.6%, P = .022) on multivariate analysis.CONCLUSIONS:
Cerebrovascular accident occurs in a low proportion of individuals within 1 year following HZO. Antiviral treatment for HZO may reduce the risk of subsequent CVA when given within 72 hours of rash onset.
