Purpose:
To investigate platelet-to-lymphocyte ratio (PLR) in retinal vein occlusion (RVO) patients.
Methods:
In this study, we retrospectively reviewed data of 32 patients with RVO (RVO group) and 32 age- and sex-matched participants without RVO (control group) between January 2017 and March 2019. The PLR was determined by dividing the platelet count by the lymphocyte count.
Results:
Age and gender were comparable between the groups (p = 0.204 and p = 0.800, respectively). PLR was significantly elevated in the RVO group compared with the control group (137 (113-164) vs 101 (86-129), p = 0.001)). In the receiver operator characteristics curve analysis, the optimal cut-off value of PLR for predicting RVO was 123, with 69% sensitivity and 72% specificity.
Conclusion:
We report that PLR are elevated in RVO, suggesting that PLR may be a useful marker for RVO.
