Join us for an insightful conversation with two leading experts in eye care, Dr. Jennifer Lyerly and Dr. Mark Dunbar, as they shed light on the often-overlooked topic of geographic atrophy. Historically, geographic atrophy presented challenges with limited treatment options, but recent scientific breakthroughs have brought newfound hope. With decades of experience and expertise, Dr. Dunbar, from the prestigious Bascom Palmer Eye Institute, shares his insights. Dr. Lyerly guides the discussion, exploring prevalence, detection challenges, early intervention, and the pivotal role of advanced imaging.
