Play Later Play Later Lists Like LikedTAG #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.

I'm still digging through the vaults to post episodes like this gem and have a few more that will go live soon. Email me at podcast@iguy.org if you would like to be on the show to discuss a topic in glaucoma or if you have questions that you would like to have answered on a future episode. Check out WestCoastGlaucoma on Instagram https://instagram.com/westcoastglaucoma for some short-form videos that can also be found on my robschertzer YouTube channel. https://youtube.com/robschertzer . In this episode, I talk with Gus DeMoraes, a frequent guest of the pod. Gus is Associate Professor of Ophthalmology at Columbia University where he serves as Medical Director of Clinical Trials. When we originally sat down to record this way back in March 2019, he had just presented some of the work he had done in collaboration with Don Hood. This has now appeared on Humphrey perimeters as the 24-2C testing strategy and is becoming a new the standard of care. It is based on reports in recent years that glaucoma damage often occurs in the macular area but missed because the standard 24-2 testing strategy only tests in 6 degree increments. These early central glaucomatous defects are often hidden between the test points. Listen in as I talk with Gus. I'm Rob Schertzer, a Vancouver, Canada based glaucoma specialist, podcaster and HealthIT expert, and we're...talking about glaucoma.

Play Later Play Later Lists Like LikedIntro: Welcome back to Talking About Glaucoma, a podcast of indeterminate length and frequency. I’m your host Robert Schertzer, a Glaucoma Specialist from Vancouver, BC Canada. To help produce future shows more frequently, I will no longer include artwork and chapter markings. Hopefully this will get me back on track to publishing new episodes each month this coming year. As always, contact me at podcast@iguy.org if you have a glaucoma topic that you would like to discuss with me on a future episode. In this episode, I talk with Murray Johnstone from Seattle about pulsatile flow through the Trabecular Meshwork and collector channels. We discuss the imaging improvements over the years that have made this possible including the latest phase-based OCT scans that result in nanometre resolution instead of the micrometre resolution of spectral domain scans that most of us are using in clinical practice. Show Notes: This topic spans decades of work that began prior to his fellowship and resumed around the year 2000 as the imaging technology began to become available to prove the theory. Aqueous outflow drugs increase the outflow pulsatility, not just flow. Goldmann thought the TM was rigid preventing he and Asher from being able to explain the pulsatile nature of the flow. The ocular pulse drives movement of the TM, which is not rigid. The drugs that improve outflow, do so by altering the blood flow to achieve their effect. This is literally a stroke volume. The theoretical sensitivity to motion is in picometer with the newer phase-based OCTs, that of the movement of electrons in an atom, though practically we achieve nanometer resolution. This is sensitivity of motion of the TM walls, and not the resolution of an image. How does this flow vary by location within the angle and from moment to moment? This is a live dynamic process. They have published numerous studies in both normal and abnormal outflow patients. Questions to answer include how this flow is altered by laser, meds, stent procedures? Does the act of doing the measurements also alter the flow? It is non-contact and non-invasive therefore should not be altering the flow but white-coat syndrome could have an influence. Perhaps in the future, we can instill a drop in the patient’s eye, measure the change in pulsatile flow, and be able to tell whether a particular medication will actually be effective. We measure 12 seconds of 31 million seconds in a patient’s year when we check IOP several times per year. By determining pulsatile outflow we have the potential to achieve new diagnostic and treatment options for our patients. This is analogous to how cardiology is using imaging modalities in patient care. Selected References for this episode related to pulsatile flow: 1. Johnstone MA, Grant WM.

Episode Chapters: Intro: Ron Fellman Glaucoma Associates of Texas Fluid Wave: what it isRelated strictly to conventional outflow Evidence of patency of this system When unroofing Schlemm’s canal a decade ago when viscocanalostomy was being popularized, injecting BSS you could see the outflow pathways At times there would be no flow into the adjacent veins Was I in the wrong spot? Five years ago during Trabectome, wondered if the outflow could be visualized Reduced the Episcleral Venous Pressure by putting patient into some raverse Trandelenberg and raised the bottle height to its highest You don’t see this during normal phacoemulsification because usually you are forcing the Schlemm’s canal closed How does the fluid get to the episclera? In Trabectome, adjacent to the tip, can see segmental fluid outflow if focus at the limbus; first let foot off the foot-pedal to drop the eye pressure and look for blood to reflux in to AC, then floor the pedal and if there’s a connection through to the collector channel, then the fluid gets through the episclera via deep venous plex, mid venous plexus and then to the episcleral venous plexus super highway Blanching is occurring as all the blood runs out of the tissue Improve outflow where there isn’t or optimize existing flow? Aqueous wants to go out the path of least resistance If you see a blanching it means the deep and mid venous plexus are both open and this is where the trabectome will work the best The blanching correlates best with the patients with the lowest IOP; averaging 11.9 on 1 med vs 19 on 3 meds Zero re-op on those with good flow vs 36% in patients with a poor wave seen intra-operatively However we still don’t have a way to modulate wound healing with a trabectome; so can still get granulation tissue that ruins the surgery Would fluid wave work for other MIGS procedures? With circumferential sclerotomy see a near uniform fluid wave With an iStent if you hit the right spot, usually won’t see more than 1 or 2 clock hours of a fluid wave; and this would only be seen AFTER the iStent is in place so you can’t do this BEFORE putting in the iStent What’s the outcome marker for MIGS surgery?

It is the preferred version for experiencing this podcast.] I sat down with Chris Johnson at a recent American Glaucoma Society meeting to discuss some of my pet peeves about visual field testing and what lies on the horizon. Chris is Professor of Ophthalmology and Visual Sciences at the University of Iowa and a world renown Perimetry expert. Episode Chapters: 1. Myopic tilted optic nerves; do we have a proper control group to compare these patients to? Liquid lens in HVF 3 corrects for spherical refractive error. Nasal steps often spill over the horizontal midline because we do not correct for tilt. SLO with microperimetry will compensate for this, not yet released at the time of this recording but is now available outside of North America e.g. Compass (Fundus Automated Perimetry) https://www.centervue.com/products/compass/ 2. Flattening of Frequency of Seeing curve as defects gets worse, the VF gets less reliable because we don’t use bigger test targets when worse; i.e. the more damage, the higher the variability. Aside from increasing target size e.g. a size VI target, there is potential with Frequency Doubling perimetry to reduce this variability 3. Patchy loss: we don’t have good macular functional testing. Patchy loss testing such as Rare Bit perimetry by Lars Frisen: Frisén, L. New sensitive window on abnormal spatial vision: rarebit probing. Vision Res. 2002;42:1931–1939. https://www.ncbi.nlm.nih.gov/pubmed/12128022 4. Home testing with tablets or smartphones 5. Reached a plateau and now that imaging has been advancing, it’s time for a paradigm shift that correlates the structure and function Production information: This episode was originally recorded March 2015 during the Annual Meeting of the American Glaucoma Society in Coronado, CA using two Shure SM58 microphones with a Marantz PMD661 digital recorder. Mixing and sound levelling were FINALLY performed in July 2017 on a MacPro using Hindenberg Journalist Pro software. Narration was overdubbed using a Heil PR40 Microphone with Journalist Pro.

It is the preferred version for experiencing this podcast.] Tom Harbin, MD In this episode, Tom Harbin, from Eye Consultants of Atlanta, and I discuss ethical issues in the medical treatment of glaucoma. This includes generic vs brand name drugs, the need to shop around for the best price, and looking out for talks from so-called Key Opinion Leaders. -------------------------------------------------- Production information: This episode was recorded live in March 2014 during the Annual Meeting of the American Glaucoma Society in Washington, DC using two Shure SM58 microphones with a Marantz PMD661 digital recorder. Mixing and sound levelling were FINALLY performed in February/March 2017 on a MacBook Pro using Levelator, and Hindenberg Journalist Pro software. Narration was overdubbed using a Heil PR40 and Audio Technica ATR2100 USB Microphone with Journalist Pro. This completes my transition from Garage Band to Hindenberg Journalist Pro which allows me to edit these shows cross-platform and hopefully will help me get episodes out more quickly like the three still awaiting release with Chris Johnson, Ron Fellman and Murray Johnstone that were recorded in 2016.

It is the preferred version for experiencing this podcast.] Tracy Wright, MD In this episode, I talk with Tracy Wright, now based at Kaiser Permanente in Washington DC. He was at the Bascom Palmer Eye Institute at the University of Miami when we recorded this conversation. The implications immediately effected how I look at visual fields in my patients but I have yet to see further studies that support what we discussed, namely that visual fields continue to progress for a long time even once the stimulus that led to the initial glaucoma damage has been removed, likely due to apoptosis. The findings you are about to here may be shocking. Please write to me with your comments. -------------------------------------------------- Production information: This episode was recorded live in March 2014 during the Annual Meeting of the American Glaucoma Society in Washington, DC using two Shure SM58 microphones with a Marantz PMD661 digital recorder.
