Comparison of Peripheral Blood Inflammatory Indices in Patients with Neovascular Age-related Macular Degeneration and Haemorrhagic Polypoidal Choroidal Vasculopathy

Purpose To compare the differences in peripheral blood inflammatory indices between patients with neovascular age-related macular degeneration (nAMD) and haemorrhagic polypoidal choroidal vasculopathy (PCV).Methods Retrospective, best corrected visual acuity (BCVA), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and monocyte-to-lymphocyte ratio (MLR), were analysed across the nAMD, PCV and normal control (NCG) groups of patients. The ratios' cut-off values for nAMD were calculated.Results nAMD had a significantly longer duration and better BCVA than PCV (all P < .05). The NLR, MLR and PLR were significantly higher in nAMD than in PCV and NCG (all P < .01), no significant differences between PCV and NCG (all P > .05). The ROC curve analysis revealed that the cut-off values for NLR and MLR were 1.98 and 0.24, respectively, for nAMD.Conclusion NLR, MLR and PLR are significantly high in patients with nAMD. The ability of these inflammatory indicators to distinguish nAMD and PCV is unclear.
