To explore opportunities for individualized postoperative positioning duration in macular hole (MH) surgery. : This post hoc analysis comprised eyes that had full-thickness MH (FTMH) repair in the prospective DISCOVER intraoperative optical coherence tomography (OCT) study. Preoperative spectral-domain OCT (SD-OCT) and postoperative day 1 (POD1) trans-tamponade OCT were analyzed. Preoperative SD-OCT macular cubes were imported and analyzed using a machine learning-enhanced segmentation platform. Nine preoperative segmentation parameters were analyzed (maximum foveal height, apex area, base area, central foveal area, maximum apex diameter, maximum base diameter, maximum depth, minimum foveal width, volume). In addition, 2 new metrics-the macular hole index and tractional hole index-were calculated. POD1 trans-tamponade OCTs were obtained and evaluated for hole closure. : Of the 66 eyes with an FTMH, 16 (24%) had a chronic MH and 5 (8%) were reoperations from FTMH nonclosure after previous surgery. Nine eyes (14%) had an open MH on POD1 trans-tamponade OCT (6 chronic MHs [66%]; 2 reoperations [22%]); the remaining 57 MHs (86%) were closed. Multiple segmentation parameters were significantly associated with POD1 closure. : Volumetric MH measurements and trans-tamponade POD1 OCT closure status are important in predicting MH closure speed and the need for postoperative positioning. Individualized positioning duration in MH could lower perioperative morbidity and vastly enhance quality of life.

Purpose: To evaluate the potency and security of Pneumatic Vitreolysis (PVL) as the primary treatment for Full-Thickness Macular Holes (FTMHs) and provide insights into patient selection criteria and procedural outcomes.
Patients And Methods: A retrospective analysis of three clinical cases presenting with FTMHs treated initially with PVL was conducted. Cases were evaluated for anatomical and functional outcomes through comprehensive ophthalmic examination and optical coherence tomography (OCT) imaging.

Purpose: Autologous retinal transplantation has been successfully employed in the treatment of large and myopic macular holes that are refractory to standard surgical treatments. Patients transplanted with a peripheral neurosensory retinal graft have shown unexpected improvements in visual acuity. The study aims to investigate if neural integration of the graft takes place in a porcine model of retinal hole.

Purpose: To investigate the incidence, clinical spectrum and pathophysiology of microcystoid macular edema (MME) in two cohorts of patients with epiretinal membrane (ERM) and idiopathic full thickness macular hole (FTMH).
Design: Single-center, Retrospective, interventional, cohort study.
Methods: Review of clinical charts, structural and en-face optical coherence tomographty (OCT) and fluorescein angiography (FA) imaging of ERM and FTMH eyes which underwent surgery with pars plana vitrectomy and internal limiting membrane (ILM) peel, with a minimum follow-up of 6 months.

Purpose: To describe the efficacy and safety outcomes of NPB macular buckle (MB) in myopic traction maculopathy (MTM).
Methods: A monocentric, prospective cohort study of the naïve eyes who underwent MB surgery, alone or combined with vitrectomy (PPV) for MTM, using the new NPB buckle, between December 2022 and June 2024. The anatomical results, postoperative complications, and MB ease of use were analyzed as the main outcomes.

Background: To investigate the anatomical and functional outcomes of macular hole-associated retinal detachment (MHRD) after vitrectomy using the inverted internal limiting membrane (ILM) flap technique with autologous blood clot (ABC).
Methods: This retrospective observational study included 80 eyes with MHRD that underwent vitrectomy with ILM flap without (46 eyes) or with ABC (34 eyes). Fundus photography and optical coherence tomography were evaluated.
