New Retina Radio by Eyetube

Co-hosts Justin C. Muste, MD, and David Fell, MD, are joined by Omesh P. Gupta, MD, retina specialist at Wills Eye Hospital, and Shane Griffin, MD, MCR, vitreoretinal surgery fellow at the University of California San Diego Shiley Eye Institute, to discuss scleral-fixating secondary IOLs. They share pearls for implantation success, advanced techniques, and tricks for handling complicated cases.

Does retinal capillary non-perfusion reliably predict functional vision loss in DR? And does the answer change how retina specialists treat it? In this episode of New Retina Radio Journal Club with VBS, Barton Blackorby, MD; Katherine Talcott, MD; and Hong-Uyen Hua, MD, discuss a prospective longitudinal cohort study examining the association between retinal sensitivity and perfusion over 2 years in patients with DR.

In this episode of RetinaLIVE, Kourous Rezaei, MD is joined by Lejla Vajzovic, MD, FASRS and Aleksandra Rachitskaya, MD, FASRS to discuss their experiences with UNITY® VCS in vitreoretinal surgery. The conversation covers instrument design, workflow, training and the integration of new technology in clinical practice, offering perspectives on collaboration and adapting to evolving surgical tools.
