In this episode, Dr Sarkisian and I discuass his use of Ologen branded collagen matrix in attempts to improve the success of glaucoma surgery. This novel modification has yet to gain widespread support and would still be considered experimental at the time of this recording. Steven R. Sarkisian, Jr., MD is the director of the glaucoma fellowship at the Dean A. McGee Eye Institute and serves as a clinical associate professor of Ophthalmology at the University of Oklahoma in Oklahoma City. Dr Sar...

Talking About Glaucoma #16 for late July 2011 - Dr Gus De Moraes, Risk factors for VF Progression in glaucoma patients In this episode, Dr De Moraes and I discuss risk factors for visual field progression in patients already diagnosed with and being treated for glaucoma. Dr De Moraes’ group found that patients with established glaucoma were more likely to progress when peak IOP was 18 mm Hg (millimeters of mercury) or higher. Other risk factors included thinning of the cornea, presence of di...

In this episode, Dr Ehrlich and I discuss baseline corneal hysteresis and its relationship with the amount of IOP reduction in prostaglandin treatment. Dr Josh Ehrlich is a fourth year medical student at the Weill Cornell Medical College in New York City. He begins his Ophthalmology residency July 2012 at the Wills Eye Institute.

In this episode, Dr Dale Heuer and I discuss the latest glaucoma surgical techniques and devices in search of solid evidence for their safety and effecacy. Trabeculectomy is the operation that we love to hate so we are always looking for something better. In some countries, new devices just require proving safety without having to show efficacy whereas in other countries both must be proven. Canaloplasty involves threaded a fibre-optic canula around the full circumference of Schlemm’s canal, usi...

Show notes Talking About Glaucoma #13 December 2010 Glaucoma Risk Factors In this episode, Dr Nicolela and I discuss the risk factors for the development of glaucoma. This includes talking about the difference between risk factors for developing disease vs those for disease to progress. Much of our current knowledge is based on information from clilnical trials and population studies over the past decade. Bear in mind that still intraocular pressure remains as the single most important modifiab...

In this episode, Mr Foster and I discuss angle closure glaucoma focusing on epidemiology, mechanism and treatment (iridotomy and cataract extraction.) Mr Paul Foster a consultant glaucoma specialist with a particular interest in angle-closure glaucoma. He runs the only specialist clinic for angle-closure glaucoma in Europe at Moorfields Eye Hospital. He has had extensive clinical and research training in glaucoma in London, Oxford and Singapore. Robert M Schertzer, MD, MEd, FRCSC Clinical Asso...

In this episode, Drs Schuman, Burgoyne and I discuss optic nerve and nerve fiber layer iimaging in glaucoma. To clarify the different modalities, the Confocal Scanning Laser Ophthalmoscope (CSLO) has been popularized as the Heidelberg Engineering device, current version being the HRT 3; the Scanning Laser Polarimeter is the GDx machine, and; the original Optical Coherence Tomography unit and its next 2 generations were popularized by Zeiss and use Time Domain scanning whereas the latest technolo...

In this episode, Dr Damji and I discuss the use of Selective Laser Trabeculoplasty (SLT) in treating patients with open angle glaucoma. The conversation includes a comparison of this to Argon Laser Trabeculoplasty (ALT), the step-wise approach to treating patients with glaucoma and where the SLT might fit it. We also cover the burning question of the repeatability of this treatment modality as well as its contraindications. Robert M Schertzer, MD, MEd, FRCSC Clinical Associate Professor Dept of...

In this episode, Dr Hom and I discuss things to consider in purchasing a Visual Field machine for your practice. We look at the choice based on the scope of your practice, networking, and sharing your data with colleagues. (See AAC version for complete show notes.)
