Assessment of Monocyte/HDL Ratio in Branch Retinal Vein Occlusion.

: 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).: 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.: The mean MHR was significantly higher in BRVO group compared to the control group (13.4 ± 5.2 vs. 8.1 ± 2.2, < 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%.: The present study showed that elevated MHR is significantly associated with BRVO. Therefore, MHR may be a useful marker for the emergence of BRVO.
