How did cells taken from one woman more than 70 years ago become one of the most important tools in modern medicine? In this Eye-Q Science Story, Dr. Rani Banik explores the life and legacy of Henrietta Lacks, whose cancer cells became the immortal HeLa cell line. The episode covers the enormous scientific impact of HeLa cells, their surprising connection to eye research, and a 2018 study that used HeLa cells to investigate retinal and blue light. Dr. Banik also explains why laboratory cell findings should not be confused with proof of disease in humans—and why the familiar claim that ordinary screen exposure “kills retinal cells” goes far beyond what that experiment established. Finally, the episode examines the ethical legacy of Henrietta Lacks: informed consent, privacy, race, medical research, and the importance of remembering the human being behind the cell line.

Could Ozempic, Wegovy, Mounjaro or Zepbound affect the optic nerve? In this special episode of The Eye-Q Podcast™, neuro-ophthalmologist Dr. Rani Banik examines the rapidly evolving evidence surrounding GLP-1–based medications and nonarteritic anterior ischemic optic neuropathy, or NAION. You’ll learn what NAION is, which patients may already be more susceptible, why optic disc anatomy and optic disc drusen matter, how diabetes and obstructive sleep apnea complicate the risk-benefit discussion, and what the major studies actually tell us. Dr. Banik also discusses proposed mechanisms, a real-world patient experience with bilateral sequential NAION, practical guidance for patients and physicians, and the recent litigation surrounding these medications. The key message: association is not the same as causation, and relative risk is not the same as absolute risk. Do not discontinue a prescribed GLP-1 medication without discussing the risks and benefits with your treating clinician.

What does functional medicine have to do with your eyes?
