ABSTRACT
PURPOSE: Retinal detachment (RD) is associated with poor visual outcome in patients with acute retinal necrosis (ARN). This research was undertaken to assess risk factors for RD in ARN.
DESIGN: Retrospective cohort study SUBJECTS: Patients diagnosed with ARN at a tertiary referral center from 2010-2020.
METHODS: Chart review was performed for all clinical and surgical encounters. Univariate and multivariate logistic analysis of demographic and clinical variables associated with RD was performed. Survival analysis with Kaplan-Meier estimates were performed to compare time to RD in HSV- and VZV-associated ARN.
MAIN OUTCOME MEASURES: Demographic information, clinical information including visual acuity, intraocular pressure (IOP), intraocular inflammation level, extent of retinitis, incidence and timing of retinal detachment, date of diagnosis, and treatments performed including intravitreal injections of antiviral medications.
RESULTS: Fifty-four eyes of 47 patients who were diagnosed with ARN were included with equal proportions of eyes (27, 50%) with VZV-ARN and HSV-ARN. Subjects with VZV-ARN were on average older, more likely to be male, and more likely to be immunosuppressed compared with subjects with HSV-ARN. Clinical characteristics were similar between eyes with VZV- and HSV-ARN, including initial visual acuity (VA), initial IOP, anterior segment inflammation, clock hours and posterior extent of retinitis. In univariate analysis of clinical and demographic variables associated with development of RD, initial VA (p = 0.0083) and greater clock hours of retinitis (p = 0.009) were significantly associated with RD. These two variables remained significant in multivariate logistic regression; worse VA at presentation had an odds ratio of 2.34 (95% CI: 1.01 – 5.44) (p = 0.042) and greater clock hours of retinitis had an odds ratio of 1.23 (95% CI: 1.02 – 1.47) (p = 0.025). Kaplan Meier survival analysis demonstrated no statistical difference in RD-free survival between HSV- and VZV-ARN.
CONCLUSION: Patients with VZV-ARN were more likely to be older, male, and immunosuppressed compared to HSV-ARN although no clear difference was observed in RD by viral etiology. Poor initial VA and clock-hours of retinitis were significantly associated with RD development and may be relevant for patient counseling and prognosis.
