Article Abstract
Purpose: To examine the prevalence of epiretinal membrane (ERM) according to the OCT-based severity scales, and to describe associations focusing on the impact of smoking and axial length of the globe.
Design: Cross-sectional study.
Participants: The baseline examination cohort comprised participants from the Tohoku Medical Megabank community cohort recruited from 2013 to 2017.
Methods: In total, 38 118 eyes of 19 486 participants were classified with ERM staging. The characteristics of ERM severity were analyzed, and the association between the prevalence of ERM and ocular and systemic parameters was investigated using logistic regression models. Cubic spline models were constructed to visualize the relationships with lifetime smoking exposure and axial lengths. Regarding ERM severity, the associations between stage 1 and stage 2 or more were analyzed with multivariate analysis.
Main Outcome Measures: Epiretinal membrane prevalence at each stage determined via OCT and factors associated with ERM presence and severity.
Results: The prevalence of ERM was 2.3% per eye (3.6% per person), with a predominance at stage 1. The presence of severe ERM stages was higher in older individuals. The multivariate logistic analysis revealed that older age, female sex, and long axial length were associated with a higher prevalence of ERM. In a multivariate analysis stratified by sex, glaucoma was also identified as a significant factor associated with the prevalence of ERM in women. In the cubic spline model, no consistent trend was observed between smoking and ERM prevalence. However, a U-shaped relationship was indicated between axial length and ERM prevalence. Epiretinal membrane severity highlighted older age, alcohol consumption, and very long axial length as significantly associated compared with stage 1.
Conclusions: Epiretinal membrane prevalence was significantly associated with older age, female sex, and long axial length.

Objective: To describe observed intraocular pressure (IOP) changes following vitrectomy (PPV) surgery and PPV combined with phacoemulsification in eyes with and without glaucoma.
Methods: A total of 20,894 patients from the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) who underwent vitrectomy surgery for epiretinal membrane or vitreous opacities from January 2016 to March 2023 were included. Mean IOPs from postoperative day 1, days 2-10, days 11-30, and then monthly through 6 months were compared to baseline.

Purpose: To compare the long-term safety of MicroShunt implantation with trabeculectomy in eyes with primary open-angle glaucoma (POAG).
Methods: This was a 3-year observational extension of a 2-year prospective randomized trial comparing clinical outcomes of MicroShunt implantation with trabeculectomy, both augmented with mitomycin C. Adverse events (AEs), intraocular pressure (IOP), and IOP-lowering medication use were recorded 36, 48, and 60 months after initial randomization.

We report a case of a young woman who presented with a vitreous haemorrhage associated with a combined hamartoma of the retina and retinal pigment epithelium (CHRRPE). During her clinical course, while the vitreous haemorrhage resolved, the lesion enlarged with a worsening epiretinal membrane. The patient's visual acuity reduced from 0.

Purpose: To investigate the rate and progression of epiretinal membrane (ERM) formation following scleral buckling (SB) for rhegmatogenous retinal detachment (RRD).
Methods: A retrospective review of eyes undergoing SB for RRD repair between January 2015 and June 2022 that developed ERM. ERM grading and structural analysis were performed using spectral domain optical coherence tomography (SD-OCT) based on a standardized scheme.

The epiretinal membrane (ERM) is a fibrocellular layer that forms on the inner surface of the retina, often leading to visual impairment and significantly impacting visual function. Understanding the pathophysiology of ERM formation is crucial for advancing ophthalmic care and improving patient outcomes. This research aims to investigate the pathophysiology of ERM by comparing the internal limiting membrane (ILM) pathology in patients with and without ERM.
