{Abstract}: <B>UNASSIGNED: </B>In this study, we aimed to evaluate cellular alterations in the foveal neuroglia of eyes with idiopathic epiretinal membrane (ERM) and examine their correlation with visual function. We also aimed to identify prognostic markers for visual outcomes postvitrectomy.<BR><B>UNASSIGNED: </B>A prospective longitudinal study.<BR><B>UNASSIGNED: </B>The study comprised 84 subjects, including 50 eyes diagnosed with idiopathic ERM and 34 healthy eyes serving as controls.<BR><B>UNASSIGNED: </B>The foveal neuroglial changes in eyes with idiopathic ERM were determined using adaptive optics OCT (AO-OCT) by comparing them with healthy eyes. For patients with ERM, the ERM and inner limiting membrane were removed during vitrectomy in all eyes.<BR><B>UNASSIGNED: </B>Foveal microstructures on AO-OCT images, best-corrected visual acuity (BCVA) and M-CHARTS scores, evaluated preoperatively and at 1, 3, and 6 months postoperatively, and associations between foveal neuroglial changes and these parameters.<BR><B>UNASSIGNED: </B>Adaptive optics OCT revealed discernible differences in the foveal cones of the eyes with ERM and their healthy counterparts. The thickness of the ellipsoid zone (EZ) band was augmented in eyes with ERM. The alignment of the Müller cells was more vertical and the density of the foveal cone cell nuclei was higher in eyes with ERM than in healthy eyes. Within the AO-OCT parameters, the higher cone nuclei count correlated with worse M-CHARTS scores, both preoperatively and 6 months postoperatively (P = 0.004, 0.010, respectively). Greater EZ thickness was significantly associated with poorer 6-month postoperative BCVA (P = 0.005).<BR><B>UNASSIGNED: </B>Adaptive optics OCT can be used to precisely identify cellular alterations in eyes with ERM that are closely related to visual function impairments. These cellular insights enhance our understanding of ERM pathology and offer promising prognostic indicators of visual outcome after vitrectomy.
