Gaining global consensus on DME needs will dictate the terms of future drug development. Can the findings from the DME AWARE Delphi study help? Baruch Kuppermann, MD, PhD, joins the show to review the findings from a 25-doctor panel of global experts. What did they conclude regarding the unmet needs in DME?

When do symptomatic vitreous floaters warrant surgery, and when is observation sufficient? In this episode of New Retina Radio Journal Club with VBS, host Kyle Kovacs, MD, joins Matthew Starr, MD, and Neda Valikodath, MD, to review a major study on vision-degrading myodesopsias from vitreous floaters. They then debate the risks and value of limited refractive vitrectomy for select patients in real-world settings, and review their protocols for patients who present with floaters.

Co-hosts David Fell, MD, and Justin C. Muste, MD, sit down with Allen C. Ho, MD, director of Retina Research at Wills Eye Hospital, and Curtis Heisel, MD, MBA, a vitreoretinal surgery fellow at the University of California San Diego, to discuss the gene therapy landscape in retina. They share their journeys in the space, the therapies under investigation, and how fellows can get involved.
