TAG #35 GEDDE Steve - Glaucoma surgical trials: lessons learned
Intro:
There have been many trials proving surgical intervention does indeed reduce the risk of progressive glaucoma damage for our patients. These include Treatment vs No Treatment studies as well as studies that compare different types of treatment. In this episode, I talk with Steve Gedde, from the University of Miami's Bascom Palmer Eye Institute, about lessons learned from these clinical trials.
We begin by discussing the importance of Randomized Clinical Trials as the highest evidence-based medicine to compare treatments.
Studies that we discuss include: the Fluorouracil Filtering Study Group; Tube vs Trab (TVT); Primary Tube vs Trab (PTVT); Ahmed Baervedlt Comparison (ABC); Ahmed vs Baerveldt.
Some of the concepts and lessons learned include: reducing IOP prior to surgery to lessen the risk of choroidal hemorrhage from a sudden IOP drop; trabeculectomy offering titratable control that MIGS procedures do not; that it's harder to get a 20% reduction in IOP to count as a success if the IOP is lower than 25 pre-op; that Ahmed Valves have a better safety record but Baerveldt better pressure-lowering; and that antimetabolites have been shown to NOT be effective for tube-shunt surgery.
There's quite a bit of information packed into this episode so I suggest checking the program notes for links to some relevant articles and presentations related to this topic.
I'm Rob Schertzer, a Vancouver, Canada based glaucoma specialist, podcaster and HealthIT expert, and we're...talking about glaucoma.

We spoke in February 2020, one of three interviews I recorded at the last in-person American Glaucoma Society annual meeting prior to Covid. My apologies that all of these recordings were made using BOYA Dual Lapel USB-C BY-M3D mics plugged into an Android phone instead of my usual professional set-up. I've done my best to make the audio quality acceptable but the sound quality is not up to my usual high standards. Fortunately there is just one more episode with this low quality...so be sure to subscribe so you can get the good stuff when available.

Production information:
This episode was recorded February 29, 2020 during the Annual Meeting of the American Glaucoma Society in Washington, DC, unfortunately using a BOYA Dual Lapel USB-C Microphone BY-M3D - which I do not recommend. Mixing and sound levelling were finally completed to salvage the recording on February 21, 2022 using Hindenberg Journalist Pro software iZotope processing plug-ins on a Gigabyte AERO 17 computer. The narration was overdubbed using a Heil PR40 microphone.
Opinions expressed in this podcast are those of the speakers and are not intended to be taken as the standard of care for glaucoma treatment. Please always weigh the complete clinical picture and involve patients with any decisions in their care.
