Neutrophil‐to‐lymphocyte ratio and platelet‐to‐lymphocyte ratio in retinal vein occlusion

Abstract

Background

To evaluate the association between neutrophil‐to‐lymphocyte ratio (NLR), platelet‐to‐lymphocyte ratio (PLR) and the development of retinal vein occlusion.

Methods

One hundred and eleven patients and 88 control subjects were enrolled. Retinal vein occlusion diagnosis was clinically made with fundus examination. NLR and PLR values were compared between groups.

Results

Neutrophil levels were found to be comparable between the two groups (p = 0.47). Lymphocyte levels were lower in retinal vein occlusion patients (p = 0.001). NLR was significantly higher in retinal vein occlusion patients (p = 0.001). Platelet counts were found to be comparable in the two groups (p = 0.75). PLR was significantly higher in retinal vein occlusion patients (p = 0.001). According to the receiver operating characteristic curve analysis, the optimal cut‐off values of NLR and PLR to predict retinal vein occlusion were > 1.63 and > 98.50, respectively.

Conclusions

The present study showed that higher NLR and PLR were associated with the development of retinal vein occlusion. Also, NLR and PLR may be used as predictive tools for identifying risk for retinal vein occlusion.
