Purpose: The role of systemic steroids in the treatment of ophthalmoplegia in the setting of herpes zoster ophthalmicus (HZO) is controversial. We conducted a case report-based meta-analysis to investigate the role of systemic steroid in the recovery of efferent dysfunctions in HZO.
Design: Case-report based meta-analysis.
Method: We report a case of herpes zoster ophthalmicus-related ophthalmoplegia (HZORO) in which systemic steroid led to complete resolution of external ophthalmoplegia. We further identified subjects from published cases of HZO-related ophthalmoplegia by searching PubMed and Google Scholar, which elicited 42 articles (49 cases) after excluding those younger than 18 years or with incomplete follow-up data. With the present case, a total of 50 cases are included in the analysis. Main outcome measure is the recovery of efferent dysfunction at the last known follow-up, coded as 1 for complete recovery or 0 for noncomplete recovery. We performed multivariable linear regression and Cox proportional hazards analysis to determine the contribution of steroid duration on the status of complete recovery.
Results: Multivariable linear regression showed significant association between duration of steroid treatment and status of complete recovery (P < .001). Cox proportional hazards analysis showed a hazard ratio of 1.1 (P = .04), indicating that longer treatment duration increased chance of complete recovery. Age, gender, and initial steroid dose did not contribute significantly to recovery status.
Conclusion: Our meta-analysis suggests that extended steroid taper may aid the recovery of ophthalmoplegia in the setting of HZO and should be investigated further in the future.
