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.

Purpose: The purpose of this article was to evaluate monocyte count and high-density lipoprotein (HDL) cholesterol levels and their ratio (monocyte/HDL ratio [MHR]) in patients with branch retinal vein occlusion (BRVO).Materials and Methods: A total of 50 participants were included in the study. Participants were divided into two groups: Twenty-five patients diagnosed with BRVO and 25 participants as the control group. Ocular examination findings and hematologic parameters were accessed from the file records and database, retrospectively.Results: The mean MHR was significantly higher in BRVO group compared to the control group (13.4 ± 5.2 vs. 8.1 ± 2.2, p < 0.001). In receiver operating characteristics analysis, the area under the curve for MHR was 0.862, and an MHR of >9.5 predicted BRVO with a sensitivity of 76% and specificity of 70.8%.Conclusion: The present study showed that elevated MHR is significantly associated with BRVO. Therefore, MHR may be a useful marker for the emergence of BRVO. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the association between monocyte count/high-density lipoprotein (HDL) ratio (MHR) and lymphocyte count/monocyte count ratio (LMR) with pseudoexfoliation syndrome (PEXS) and pseudoexfoliation glaucoma (PEXG).Materials and Methods: A total of 63 participants included in the study. Participants were divided into three groups. Twenty-one patients with PEXS regarded as group 1, 21 patients with PEXG regarded as group 2 and 21 participants without PEXS or PEXG regarded as the control group. Blood parameters were accessed from file records and database retrospectively.Results: The mean MHRs were significantly higher in group 1 and group 2 (p = 0.003, p = 0.036) than the control group, whereas there was no difference between group 1 and group 2 (p = 0.686). The mean LMRs were lower in group 1 and group 2 than the control group but the difference was insignificant (p = 0.232).Conclusion: We found that there is an association between higher MHR and lower LMR with PEXS.
