Assessment of platelet-to-lymphocyte ratio in patients with retinal vein occlusion.
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.
