Comparison of Visual Outcomes of Nonarteritic Anterior Ischemic Optic Neuropathy in Patients with and without Diabetes Mellitus

The VA at presentation and at final follow-up in diabetic patients with NAION were not significantly different from nondiabetic controls, although diabetic patients had a higher prevalence of cardiovascular risk factors. Ischemic heart disease and greater age, but not diabetes, independently correlated with worse VA outcome.
