Assessment of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and mean platelet volume in patients with idiopathic epiretinal membrane

Purpose: To assess the role of inflammation in the pathogenesis of idiopathic epiretinal membrane (iERM) using the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV) as indicators of inflammation and to compare these parameter levels between iERM and control subjects. Methods: We retrospectively analyzed the medical records of 36 patients who underwent vitrectomy-ERM peeling and 39 patients who had cataract surgery. We obtained blood samples from all individuals who participated in the study to investigate these parameters. Results: Seventy-five subjects were included in this study: 36 in the iERM group and 39 in the control group. The mean neutrophil and MPV levels were significantly higher in iERM subjects than in control subjects. The mean lymphocyte level was lower in the iERM group. The mean NLR, PLR, and MPV levels were higher in iERM subjects than in control subjects. Conclusion: The higher NLR, PLR, and MPV levels found in patients with iERM may indicate that subclinical systemic inflammation may associate with iERM.
