Assessment of Red Cell Distribution Width, Platelet/lymphocyte Ratio, Systemic Immune-inflammation Index, and Neutrophil/lymphocyte Ratio Values in Patients with Central Retinal Artery Occlusion

ABSTRACT

Purpose

To evaluate complete blood count (CBC)-derived inflammatory indices in central retinal artery occlusion (CRAO).

Methods

A total of 42 patients with CRAO (CRAO group) and 42 age- and sex-matched subjects without CRAO (Control group) were included. CBC parameters including red cell distribution width (RDW) levels were assayed. Platelet/lymphocyte ratio (PLR), systemic immune-inflammation index (SII) and neutrophil/ lymphocyte ratio (NLR) were calculated.

Results

RDW, PLR, SII and NLR values were significantly higher in CRAO group than control group [15.2 ± 1.47% vs 13.96 ± 1.13% (p < .001), 127.94 ± 48.21 vs 101.16 ± 24.84 (p = .008), 667.11 ± 357.84 vs 493.44 ± 207.07 (p = .008), 2.70 ± 1.27 vs 2.13 ± 0.83 (p = .018), respectively]. In multivariate analysis only RDW was independent predictor for CRAO (OR 2.317, p < .001). On ROC analysis, area under curve of RDW, PLR, SII, and NLR for CRAO were 0.761, 0.685, 0.622 and 0.618, respectively.

Conclusion

RDW seems superior to other inflammatory indices to predict CRAO.
