Objectives To explore the changes of some peripheral blood cells related to inflammation in patients with non-arteritis central retinal artery occlusion (NA-CRAO). Methods A retrospective clinical study. From July 2019 to July 2021, a total of 218 patients with NA-CRAO hospitalized (NA-CRAO group) in Department of Ophthalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) and 218 patients with routine physical examination (control group) during the same period were included in the study. There were no significant differences in age (t=0.60), sex composition ratio (χ2=0.83) and body mass index (t=0.77) between the two groups (P＞0.05). 0.2 ml fasting peripheral blood was collected from the subject, and white blood cells (WBC), neutrophils (NEUT), lymphocytes (LYMPH), red blood cells (RBC), RBC distribution width (RDW), platelets (PLT), mean PLT volume (MPV), and large PLT ratio (PLCR) were detected. The NEUT/LYMPH ratio (NLR) and PLT/LYMPH ratio (PLR) were calculated. t test was used to compare measurement data between groups. Multiple logistic regression analysis was performed for blood cells with P＜0.05. The receiver operating characteristic curve (ROC curve) was used to calculate the area under the curve (AUC) and 95% confidence interval (95%CI) of each inflammatory indicator, and the optimal cutoff value was determined according to the Jorden index (sensitivity+specificity－1). Results Compared with control group, WBC, NEUT, NLR, RDW, PLR were increased in NA-CRAO group, while RBC and LYMPH were decreased, with statistical significance (t=9.68, 12.43, 9.47, 3.64, 5.54, 5.18, 0.46; P＜0.001). There was no significant difference in PLT, MPV and PLCR between the two groups (t=0.32, 1.56, 0.84; P＞0.05). Multivariate logistic regression analysis showed that NLR was a possible risk factor for the occurrence of NA-CRAO (odds ratio=2.51, 95%CI 0.780-0.859, P=0.031). ROC curve analysis showed that the AUC predicted by NLR was 0.819, the optimal critical value was 3.05, and the sensitivity and specificity were 59.2% and 92.7%, respectively. Conclusions In peripheral blood cells of NA-CRAO patients, NEUT is significantly increased and LYMPH is decreased. NLR is a possible risk factor for NA-CRAO.
