Abstract:
Purpose:To evaluate the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) in patients with non-arteritic anterior ischemic optic neuropathy (NAION).
Methods:Fifty-six patients with NAION and 60 age-sex matched healthy controls were included in the study. Demographic characteristics and laboratory findings of the patients and the controls were obtained from the electronic medical records. NLR, PLR, MLR, and SII were calculated and compared between the groups. Cutoff values were also determined.
Results:Neutrophil, monocyte and platelet counts were higher in the NAION group than in the control group, but the difference was not statistically significant (p > 0.05). The mean NLR and SII were higher in the NAION group than in the control group (p = 0.004 and p = 0.011, respectively). In the receiver operating characteristic curve analysis, the areas under the curve for NLR were 0.67, and NLR >1.79 predicted NAION with a sensitivity of 71% and specificity of 59%. The areas under the curve for SII was 0.66, and SII of >417 predicted NAION with a sensitivity of 71% and specificity of 49%. There was no significant difference in PLR and MLR between the groups (p = 0.105 and p = 0.347, respectively).
Conclusions:The current study demonstrated that NAION patients had increased NLR and SII levels compared with control subjects. Elevated NLR and SII might serve as readily available inflammatory predictors in NAION patients.
