Objective: To evaluate monocyte/high-density lipoprotein cholesterol ratio (MHR) and neutrophil/lymphocyte ratio (NLR) in patients with keratoconus (KC).
Methods: Thirty-one patients with KC (group 1) and 31 healthy control subjects (group 2) were included in the study. All participants' ocular examination findings, clinical and laboratory parameters were obtained from file records and laboratory archives.
Results: When group 1 was compared with group 2, MHR (13.7 ± 5.0 vs. 9.1 ± 3.7; p < .001) and NLR (2.3 ± 0.8 vs. 1.7 ± 0.6; p < .001) were statistically significantly higher in group 1. Optimal MHR cutoff value for KC was calculated as 10.2 with 77.4% sensitivity and 64.5% specificity, and optimal NLR cut-off value for KC was found as 1.9 with 71.4% sensitivity and 55% specificity.
Conclusion: MHR and NLR values recognized as indicators of oxidative stress and systemic inflammation were significantly higher in patients with KC compared to the control group.
