Background:
Acute retinal necrosis (ARN) is a fulminant necrotizing vaso-occlusive retinitis associated with a high incidence of vision loss. Prognostic factors associated with the treatment of ARN have not been comprehensively identified. This study aimed to determine therapeutic prognostic factors associated with long-term clinical outcomes in eyes with ARN.
Methods:
This retrospective cohort study included patients with ARN who were treated between 2005 and 2019 in two tertiary ophthalmology departments in Seoul, Korea. Multiple logistic regression analysis was performed to investigate prognostic factors associated with late-onset retinal detachment (RD) and vision loss (<20/200).
Results:
Sixty-one eyes with ARN with an average follow-up of 63.5 months were included. Surgical intervention of vitrectomy (odds ratio [OR], 0.04; 95% confidence interval [CI], 0.004-0.47) and intraoperative prophylactic laser use (OR, 0.14; 95% CI, 0.02-0.81) were independently associated with a decreased risk of late RD. The factors independently associated with an increased risk of vision loss were worse initial visual acuity (OR, 3.28; 95% CI, 1.50-7.21), zone 1 involvement of necrotic retinitis (OR, 10.84; 95% CI, 1.62-72.41), and late-onset RD (OR, 5.38; 95% CI, 1.92-31.54).
Conclusion:
Vitrectomy and/or prophylactic intraoperative laser treatment may be effective treatment options in preventing delayed RD associated with an increased risk of vision loss in eyes with ARN.
