Risk of Stroke After Nonarteritic Anterior Ischemic Optic Neuropathy

We are interested to read the study led by Park and associates1 about the risk of stroke in patients with nonarteritic anterior ischemic optic neuropathy (NAION). According to this retrospective cohort study, 1125 NAION patients were identified from January 1, 2004 to December 31, 2013, based on the Korean National Health Insurance Service (NHIS) –National Sample Cohort (NSC) database. The occurrence of incident NAION was associated with an increased risk of subsequent stroke in model 1 (crude analysis; hazard ratio [HR] = 1.31; 95% confidence interval [CI], 0.89–1.92), model 2 (adjusted analysis for demographics; HR = 1.19; 95% CI, 0. 81–1.75), and model 3 (adjusted analysis for demographics, comorbidity, co-medication, and the Charlson index score; HR = 1.10; 95% CI, 0.75–1.62), respectively.
