Dr. Joseph Allen is honored to interview one of his former professors, Dr. Carolyn Majcher, to discover how she got into optometry and ultimately academia. She shares her research around optical coherence tomography (OCT) and OCT angiography (OCT-A), then breaks down the basics of OCT-A and how to use it to diagnose diabetic retinopathy and macular degeneration. They also discuss the exciting advances in the treatment of geographic atrophy and the realities of practicing rural optometry.
