Eye doctors in Boston have started to notice a small but worrisome uptick in cases of a rare type of sudden blindness among patients taking semaglutide. (Semaglutide is the active ingredient in two Novo Nordisk drugs: Ozempic for type 2 diabetes and Wegovy for obesity.) Rare, and notableThe number of patients on semaglutide who developed NAION was tiny: Out of more than 16,000 eye patients in Massachusetts included in this six-year retrospective investigation, only 37 people on semaglutide developed NAION. Patients with diabetes and high blood pressure have always been at an increased risk of developing eyesight issues. (Novo Nordisk is working on another, separate study, testing whether semaglutide might be useful in treating diabetic retinopathy.)

CNN —People who take Ozempic or Wegovy may have a higher risk of developing a rare form of blindness, a new study suggests. The condition is relatively rare — up to 10 out of 100,000 people in the general population may experience it — but the doctors noted three cases in one week, and each of those patients was taking semaglutide medications. The risk was found to be greatest within the first year of receiving a prescription for semaglutide. Semaglutide prescriptions have soared in the US, which could raise the number of people at risk for a potential side effect. But the large number of people who are taking semaglutide should raise confidence that the absolute risk of developing NAION as a result is rare.
