Flow characterization and structural alterations in Ahmed glaucoma FP7 tubes after in-vitro aging in silicone oil.

Purpose: Patients with intraocular silicone oil (SO) display higher odds of surgical failure after Ahmed glaucoma valve (AGV) implantation compared to patients without SO. However, the structural impact of SO exposure on silicone-made AGV tubes and the resulting changes in flow rate remain unexplored. This in-vitro study evaluated changes in tube dimensions and flow rates of AGV FP7 tubes after SO exposure to inform clinicians how such changes may impact AGV functionality.

Method for Quantitative Analysis of Vitreoretinal Adhesion in Ex Vivo Model.

Purpose: Posterior vitreous detachment (PVD) is implicated in numerous retinal pathologies. A necessary step in developing new therapies, an area of significant interest, is a quantifiable assessment of posterior vitreous adhesion (PVA) that is also clinically relevant.

Methods: A 23-gauge vitrector was used at varying levels of vacuum to attempt PVD induction in a porcine eye model injected with either balanced salt solution (BSS) (control) or plasmin (2, 3, or 5 U), which can pharmacologically induce PVD.

Rethinking Prehospital Response to Mass Casualty Events: Move, Treat, and Transport.

Herein, we present a simplified approach to prehospital mass casualty event (MASCAL) management called "Move, Treat, and Transport." Prior publications demonstrate a disconnect between MASCAL response training and actions taken during real-world incidents. Overly complex algorithms, infrequent training on their use, and chaotic events all contribute to the low utilization of formal triage systems in the real world.

Targeting the Tie-2 Receptor With Faricimab in Central Serous Chorioretinopathy: A Case Series Motivated by a Genetic Finding.

Purpose: To investigate the effects of faricimab, a bispecific antibody targeting VEGF and Ang-2 (thus increasing Tie-2 activity), in patients with CSC based on a recent genetic study that implicated Tie-2 signaling in CSC pathophysiology.

Design: A retrospective interventional multicenter case series.

Methods: We included patients with chronic CSC (persistent or recurrent SRF for ≥6 months) who received at least one faricimab 6 mg injection between January 1 2022, and April 1 2024,.

Limitations of Triage in Military Mass Casualty Response: A Case Series.

Introduction: Mass casualty events (MASCALs) in the combat environment, which involve large numbers of casualties that overwhelm immediately available resources, are fundamentally chaotic and dynamic and inherently dangerous. Formal triage systems use diagnostic algorithms, colored markers, and four or more named categories. We hypothesized that formal triage systems are inadequately trained and practiced and too complex to successfully implement in true MASCAL events.
