Wegovy May Elevate Rare Eye Stroke Risk, Study Finds
A large look at FDA adverse-event data suggests Wegovy (high-dose semaglutide) has a rare link to NAION, an “eye stroke” that can cause sudden vision loss, with men at higher risk than women. Wegovy shows a stronger association than Ozempic, possibly due to rapid weight loss and blood‑pressure fluctuations, but the overall risk remains very small and more research is needed.
