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.)
