Abstract
PURPOSE: The purpose of this study was to evaluate systemic endothelial function in elderly hypertension patients with non-arteritic anterior ischaemic optic neuropathy (NAION) by using a noninvasive physiological method: endothelium-dependent, flow-mediated vasodilation (FMD). METHODS: Forty-two systemic hypertension patients with NAION (NAION group), 64 age- and sex-matched patients with systemic hypertension and no other ocular disease (hypertension group), and 100 age- and sex-matched healthy volunteers (normal group) were enrolled. FMD was evaluated using a high-resolution ultrasonography. Traditional cardiovascular risk factors and vascular parameters were measured. RESULTS: Systolic blood pressure and diastolic blood pressure were significantly higher in patients with NAION compared with the control groups (p < 0.001). The FMD decreased significantly in the NAION group (6.02 ± 1.87 %) compared to in the hypertension group (7.86 ± 2.94 %, p < 0.001) and the normal group (8.99 ± 2.44 %, p < 0.001). By multivariable logistic regression analysis, FMD was significantly associated with NAION (OR, 1.79; 95%CI, 1.67-2.01). CONCLUSIONS: NAION may be associated with systemic vascular endothelial dysfunction. FMD might be useful in the treatment monitoring of NAION.
