Evaluation of Pseudophakic Patients with Epiretinal Membrane: Our Experience
Abstract
Introduction:The aim of this study was to evaluate the clinical features of pseudophakic patients with idiopathic epiretinal membrane (ERM) and to compare the optical coherence tomography (OCT) macular characteristics of the eye with ERM with the normal eye.Methods:Patients with bilateral pseudophakic eyes and ERM in one eye who were admitted to our clinic between 2017 and 2018 were evaluated according to gender, age, visual acuity and OCT findings and the relationship between these findings were evaluated statistically.Results:Eighty-two eyes of 41 patients with a mean age of 71.4±6.4 years (range: 60-86) who were admitted to our clinic between 2017 and 2018 were included in the study. All eyes were pseudopkahic. The patients with systemic and ocular disease history were not excluded. Nineteen (46%) patients were female and 22 (54%) were male. ERM was on the right side in 21 (51%) eyes and on the left side in 20 (49%) eyes. The mean visual acuity of the eyes with ERM was 0.35±0.24 (0.1-1.0) LogMAR. The mean central macular thickness of the eyes with ERM was 355.4±75.4 (234-554) microns. Regarding the parafoveal region (1-3 mm), the superior quadrant thickness was 371.4±60.3 (range: 287-558) microns, nasal quadrant thickness was 371±52.5 (range: 311-549) microns, inferior quadrant thickness was 365.6±44.3 (range: 307-494) micron and temporal quadrant thickness was 365.1±52.2 (range: 280-510) micron. In the eyes with ERM, the macular volume was 11.3±1.1 (9.7-15) mm3 by OCT. There was a statistically significant difference between eyes with and without ERM in terms of central macular thickness, macular volume, superior, temporal, inferior and nasal quadrant thicknesses of parafoveal region (1-3 mm) (p<0.05).Conclusion:ERM is a disease related to advanced age. Since the disease occurs at the vitreoretinal interface, it causes some changes in optic cohorence tomography.
