Assessment of systemic inflammatory response index and other inflammatory indicators in retinal vein occlusion.

Abstract

Retinal vein occlusion (RVO) is the second most common retinal vascular disease after diabetic retinopathy. The study aimed to evaluate the association and the predictive value of inflammatory indicators in RVO. Sixty patients with RVO and 60 healthy individuals were enrolled in this retrospective study. Inflammatory indicators and other hematological parameters obtained from the peripheral venous sample were analyzed and compared among groups. White blood cell count (P = .003), neutrophil (P < .001), neutrophil-to-lymphocyte ratio (NLR) (P < .001), monocyte-to-lymphocyte ratio (MLR) (P < .001), platelet-to-lymphocyte ratio (PLR) (P = .014), systemic immune-inflammation index (SII) (P < .001), and systemic inflammatory response index (SIRI) (P < .001) were significantly higher; the lymphocyte count (P < .001) was significantly lower in patients with RVO. According to receiver operating characteristic analysis, NLR was significant at the good level (area under the curve [AUC] = 0.817, P < .001); SIRI, SII, and MLR were significant at the fair level (AUC = 0.774, P < .001; AUC = 0.733, P < .001, and AUC = 0.724, P < .001, respectively) and PLR (AUC = 0.630, P = .014) was significant at the weak level in terms of RVO prediction. SIRI was superior to other indicators, except NLR, to predict RVO. SIRI, NLR, SII, MLR, and PLR can be used as predictors for identifying the risk of RVO.
