Inflammatory markers of complete blood count in Fuchs uveitis syndrome

To evaluate inflammatory indices of complete blood count (CBC) in patients with Fuchs uveitis syndrome (FUS), and to compare the results with healthy individuals.Cross-sectional, comparative study.A total of 140 participants were included in the study and divided into 2 groups: 70 patients diagnosed with FUS (FUS group) and 70 healthy individuals (control group).The groups were compared in terms of ocular examination findings and CBC parameters. The independent samples t test was used to examine variables between the groups. The Pearson correlation test was performed to analyze correlation among the severity of anterior chamber reaction, duration of FUS, and CBC indices.The mean lymphocyte count and lymphocyte-to-monocyte ratio (LMR) were significantly higher in the FUS group than in the control group (p = 0.001 and p0.001, respectively). The mean monocyte count and neutrophil-to-lymphocyte ratio (NLR) were significantly lower in the FUS group than in the control group (p = 0.010 and p = 0.003, respectively). In the receiver operating characteristic curve analysis, the area under the curve (AUC) for LMR was 0.834, with a sensitivity of 82.6% and a specificity of 80.0%. The AUC for NLR was 0.789, with a sensitivity of 71.2% and a specificity of 70.0%. LMR was positively correlated with duration of FUS (p = 0.001, r = 0.574).Our findings suggest that decreased NLR and increased LMR values may be markers indicating impaired blood-aqueous barrier function in FUS.
