The study suggests that anti-VEGF injections alone do not cause the development of ERMs, VMA or PVD may have a prior impact on the development of ERMs in ARMD, and peripheral retinal degenerations and vitreomacular adhesion are related to the development of ERMs and the pathogenesis of ARMD.
Background The purpose of this study is to evaluate the influence of anti-vascular endothelial growth factor (VEGF) in the appearance or progression of epiretinal membranes (ERMs) in age-related macular degeneration (ARMD) and investigate confounding factors causing ERMs. Methods Seventy-six eyes that were treated for more than 36 months from the first anti-VEGF injection were assessed. Binary logistic regression analysis was performed between smoking, lens status, subretinal hemorrhage, posterior vitreous detachment (PVD) status, peripheral retinal degeneration, type of AMD, conditions of contralateral eye, and the number of injections as independent variables and appearance or progression of ERMs during 36 months as dependent variables. Results The presence of vitreomacular adhesion (VMA) or development of PVD during the observation period was significantly associated (Odds ratio [OR]: 5.77; 95% confidence interval [CI], 1.72-19.4; p = 0.005) with the appearance or progression of ERMs. Moreover, peripheral retinal degeneration was significantly associated (OR: 3.87; 95% CI, 1.15-13.0; p = 0.029). Injection number of anti-VEGF was not significantly associated (OR: 1.02; 95% CI, 0.90-1.16; p = 0.72). Conclusion This study suggests possibilities that anti-VEGF injections alone are unable to cause the development of ERMs, that VMA or developing PVD has a prior impact on the developing ERMs in ARMD similar to that of idiopathic ERMs, and that peripheral retinal degenerations and vitreomacular adhesion were both related to ERMs development and pathogenesis of ARMD.
