Ep 16 Talking About Glaucoma - 26Jul2011 VF progression risk fx with Gus DeMoraes (mp3)

/

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 disc hemorrhage in the retina of the eye, and atrophy in part of the eye.

Ep 15 Talking About Glaucoma - 28Mar2011: Corneal hysteresis & response to PG analogs with Josh Ehrlich (mp3)

/

In this episode, Dr Ehrlich and I discuss baseline corneal hysteresis and its relationship with the amount of IOP reduction in prostaglandin treatment. 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.

Ep 14 Talking About Glaucoma - 21Feb2011: New glaucoma devices with Dale Heuer (mp3)

/

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.

Ep 13 Talking About Glaucoma - 6Dec2010: Glaucoma risk factors with Marcelo Nicolela (mp3)

/

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 modifiable risk factor, even in normal tension glaucoma patients.

Ep 11 Talking About Glaucoma - Mar 18, 2010 Schuman & Burgoyne Imaging (mp3)

/

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 technology uses Spectral Domain technology to achieve much higher resolution with the Spectralis OCT made by Heidelberg Engineering.
