Objectives: To assess the neutrophil-to-lymphocyte ratio (NLR), mean platelet volumes (MPV), platelet–lymphocyte ratios (PLR) and other complete blood count parameters (CBC) as indicators of inflammation in patients with pterygium. Methods: This study was carried out retrospectively in 111 consecutive pterygium patients and 106 control subjects. Laboratory and clinical parameters were obtained from the patient data management system. NLR and PLR were calculated by dividing neutrophil and platelet count by lymphocyte count. Results: A significant difference was found in NLR and lymphocyte values between the pterygium and control groups (p0.05). Conclusion: NLR may have an association with pterygium, which should be investigated at larger subgroups in further studies. Keywords: Inflammation, mean platelet volume, neutrophil–lymphocyte ratio, platelet–lymphocyte ratio, pterygium
