Özet

Purpose:To iatients with neovascular age-related macular degenernvestigate the role of epiretinal membrane (ERM) on outcomes of anti-vascular endothelial growth factor therapy in pation (nAMD).Methods:This study is a retrospective observational case series and was conducted at the Gazi University School of Medicine, Ankara, Turkey. The reports of the patients with a diagnosis of new-onset nAMD, who were aged at least 50 years and treated with intravitreal anti-vascular endothelial growth factors (ranibizumab or bevacuzimab) between October 2010 and September 2013 in our retina clinic, were reviewed for the vitreomacular interface changes.Results:The study included 90 eyes of 90 patients with nAMD. The mean age of the patients was 70 7.5 years, with 35 (38.9%) being male and 55 (61.1%) being female. According to the examinations with optical coherence tomography and B-mode ultrasonography, 43 patients had concurrent vitreomacular adhesion (30 focal, 13 broad; Group 1). Twenty-nine patients had complete posterior vitreous detachment (Group 2) and 18 patients (Group 3) had ERM. The number of injections was highest for the patients with ERM (Group 3), and this difference was statistically significant (P < 0.001). The mean interval between injections and the mean longest interval were shorter in Group 3 (P < 0.05).Conclusion:The presence of ERM in association with nAMD seems to increase the number of anti-vascular endothelial growth factor injections and decrease the injection intervals for the treatment of nAMD. Although the anatomical and functional results are similar in eyes with or without ERM, the increased need for anti-vascular endothelial growth factors may mean that these membranes may decrease the penetration of the drugs through these membranes, which may act as a physical barrier. Additionally, increased inflammation in patients with ERM probably requires more frequent injections.
