RT Journal Article A1 Ueda, J. A1 Hirano, Y. A1 Yoshida, M. A1 Ogura, Y. T1 Evaluation of Visual Function and Macular Morphology Before and After Removal of Idiopathic Epiretinal Membranes JF Investigative Ophthalmology & Visual Science JO Invest. Ophthalmol. Vis. Sci. YR 2008 VO 49 IS 13 SP 4671 OP 4671 SN 1552-5783 AB To investigate whether there is a correlation between postoperative visual acuity and preoperative macular morphology in patients with idiopathic epiretinal membranes (ERM). Twenty-three eyes of 22 patients underwent vitrectomy for the peeling of idiopathic ERM. Cases with secondary ERM and macular pseudohole were excluded from the study. All patients were followed up more than 6 months after surgery. Cataract surgery was combined for the phakic eyes. The visual acuity was measured before and 6 months after the surgery. Optical coherence tomography (OCT) was performed at the same time period to evaluate the foveal thickness and macular volume. Factors affecting on the postoperative visual acuity were analyzed. Postoperative visual acuity significantly correlated with the preoperative visual acuity (P=0.0007) and the age of the patients (P=0.0015). Although there was a tendency that the foveal thickness and macular volume before the surgery were correlated with the visual acuity 6 months after the surgery, these were not statistically significant (P=0.2135, 0.1742, respectively). Positive correlation was observed between the degree of visual improvement and the foveal thickness and macular volume measured by OCT (P=0.0103, 0.0003, respectively). Preoperative evaluation of macular morphology by OCT might be useful to predict the visual function after surgery for the patients with idiopathic ERM. RD 4/22/2021
