The decision to perform a vitrectomy in a case of endophthalmitis is mainly based on the Endophthalmitis Vitrectomy Study (EVS) conclusions. An emergency vitrectomy is helpful when the baseline visual acuity is lower than hand motion perceptions. However, various coexisting conditions should be considered: clear media and the availability of an operating room dedicated to emergency surgery. These limitations lead to a frequent delay in vitrectomy to assess the progression of the initial presentation after treatment with antibiotics and anti-inflammatory agents. However, in these cases, the vitrectomy will remain restricted to the center of the vitreous cavity to limit peripheral retinovitreal traction favoring retinal detachment. Vitrectomy performed to treat the residual vitreous opacity or macular complications such as epiretinal membranes, subject to even greater delay, is another indication.

Purpose: This study evaluates the effectiveness of the inverted internal limiting membrane (ILM) flap technique during vitrectomy for treating macular hole-induced retinal detachment (MHRD) in high myopia patients, a challenging complication for vitreoretinal surgeons due to its treatment complexity.
Methods: We conducted a prospective study analyzing 92 eyes diagnosed with MHRD, all undergoing vitrectomy using the inverted ILM flap technique between February 2022 and September 2024. Successful surgery was defined as achieving retinal reattachment, macular hole closure, and improvement in visual acuity by the 12-month postoperative follow-up.

Purpose: To characterize the anterior segment (AS) morphology of patients with long-term silicone oil (SiO) in situ (> 12 months) following pars plana vitrectomy (PPV).
Methods: This prospective, comparative characterization study was conducted between January 2022 and July 2023. Patients were included and sorted based on if they had undergone PPV without long-term SiO or had SiO in situ for at least 12 months at the time of review and image collection.

: Augmented reality (AR) may allow vitreoretinal surgeons to leverage microscope-integrated digital imaging systems to analyze and highlight key retinal anatomic features in real time, possibly improving safety and precision during surgery. By employing convolutional neural networks (CNNs) for retina vessel segmentation, a retinal coordinate system can be created that allows pre-operative images of capillary non-perfusion or retinal breaks to be digitally aligned and overlayed upon the surgical field in real time. Such technology may be useful in assuring thorough laser treatment of capillary non-perfusion or in using pre-operative optical coherence tomography (OCT) to guide macular surgery when microscope-integrated OCT (MIOCT) is not available.

Purpose: To compare the efficac and safety of a dual-blade 20,000 cuts per minute (cpm) vitrectomy probe with a single-blade 10,000 cpm probe for primary rhegmatogenous retinal detachment (RRD).
Study Design: Prospective, randomized controlled clinical trial.
Methods: Evaluations were conducted preoperatively, intraoperatively, and at three months postoperatively.

Purpose: To observe the changes in the axial length (AL) in patients of acute retinal necrosis (ARN) undergoing vitrectomy and investigate the correlated factors.
Methods: Retrospective case series. Patients diagnosed as ARN undergoing vitrectomy with silicone oil (SO) tamponade, and with attached retina more than one year after silicone oil removal (SOR) were included.
