Tube Flow Shunt: An Innovative and Cost-Effective Approach to the Modified Bleb-Forming Filtration Technique
Year: 2025
Type: article
Abstract: Aiming to lower intraocular pressure, trabeculectomy remains the gold standard procedure. This report describes a novel, cost-effective modified bleb-forming filtration technique, tFlow (tube flow shunt), utilizing sterile trimmed silicone tubes from the Ahmed Glaucoma Valve (AGV), model FP7, to construct a subconjunctival filtration pathway. Here, clinical outcomes are not reported and will be evaluated in a future study. While initial findings suggest it may provide a viable alternative to other modified bleb-forming filtration techniques involving commercial devices like PreserFlo MicroShunt, EX-PRESS Glaucoma Filtration Device, and XEN Gel Stent, further investigation is necessary. Additional patient inclusion and comparative studies with different bleb-forming filtration techniques are potential areas for future research.
