Quantification of Metamorphopsia using a Smartphone-based Hyperacuity Test in Patients with Idiopathic Epiretinal Membranes: Prospective Observational Study.

Background: Quality of vision in patients with idiopathic epiretinal membranes (iERM) is closely linked to distorted vision (metamorphopsia), which is often underestimated in clinical settings. Current surgical decision-making relies heavily on visual acuity and OCT findings, which do not adequately reflect the patient's functional vision or the severity of metamorphopsia. There is a clinical need for tools that can reliably quantify this symptom to improve patient outcomes and streamline care pathways.

Diagnostic Reliability of Optical Coherence Tomography Biomarkers for Postsurgical Success in Visual Acuity in Patients with Idiopathic Epiretinal Membranes.

Introduction: Several optical coherence tomography (OCT) biomarkers for postsurgical success in patients with idiopathic epiretinal membranes (iERMs) have been described in single predictor analyses. The aim of this study was to assess the reliability of diagnosis of OCT biomarkers and to calculate their impact on postsurgical visual acuity by applying multiple regression analysis.

Methods: This retrospective study included patients scheduled for pars plana vitrectomy with membrane peeling for iERMs.
