Purpose: To report two cases of central retinal artery occlusion (CRAO) associated with vitreoretinal surgery.
Observations: Two patients underwent vitreoretinal surgery and were diagnosed with CRAO on postoperative day one. Both had received retrobulbar anesthetic blocks, followed by pars plana vitrectomy in one patient and scleral buckling in the other patient. Best-corrected visual acuity at last follow-up was 20/40 and 20/400.
Conclusions/importance: CRAO is a rare but serious adverse event after vitreoretinal surgery. The causative mechanism is not known in these patients.

Purpose Of Review: Proliferative vitreoretinopathy (PVR) is a severe complication of retinal detachment and trauma, posing significant challenges to surgical success and visual prognosis. Despite advancements in vitreoretinal surgery, PVR incidence remains unchanged, this review presents a synthesis of the principal clinical and preclinical research findings from recent years.
Recent Findings: Recent research has focused on anti-inflammatory, antiproliferative, and antifibrotic agents.
Background: To report clinical outcomes from a single-center cohort undergoing PAUL® Glaucoma Implant (PGI) surgery for secondary glaucoma after vitreoretinal surgery (VR).
Methods: Retrospective review of patients undergoing PGI surgery at the University Eye Hospital Bonn, Germany, from 04/2021 to 05/2023.
Results: 33 eyes of 33 patients were included.

Purpose To study the incidence, clinical features, microbiology, and visual outcome of endophthalmitis associated with glaucoma surgery in children at a tertiary care eye hospital in Saudi Arabia. Methods The medical records of patients <18 years of age who presented with endophthalmitis following glaucoma surgery between January 2008 and October 2018 were reviewed retrospectively. Results Endophthalmitis after glaucoma surgery was observed in 20 eyes, or 18 out of 853 eyes that underwent glaucoma surgery at our institution (2.

The SARS-CoV-2 infection manifests with diverse clinical manifestations, with severity potentially influenced by the viral variant. COVID-19 has also been shown to impact ocular microcirculation in some patients, but whether this effect varies by viral lineage remains unclear. This prospective study compared clinical features and ocular parameters assessed via optical coherence tomography angiography (OCTA) in patients recovering from SARS-CoV-2 infections during the dominance of two distinctive viral lineages, Alpha (B.
