Popular weight loss and diabetes drugs linked to increased risk of rare form of blindness – CTV

July 3, 2024

People who take Ozempic or Wegovy may have a higher risk of developing a rare form of blindness, a new study suggests. Still, doctors say it shouldn’t deter patients from using the medicines to treat diabetes or obesity.

Last summer, doctors at Mass Eye and Ear noticed an unusually high number of patients with non-arteritic anterior ischemic optic neuropathy, or NAION, a type of eye stroke that causes sudden, painless vision loss in one eye.

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.

A look back at six years of medical records showed that people with diabetes were more than four times more likely to be diagnosed NAION if they were taking a prescription semaglutide, and those who were overweight or obese were more than seven times more likely to experience the condition if they were taking the medication. The risk was found to be greatest within the first year of receiving a prescription for semaglutide.
