Patients on Ozempic are developing a rare form of sudden blindness, doctors say

• A new study suggests people on Ozempic or Wegovy may be more likely to suddenly go blind.
• The condition, called NAION, is still exceedingly rare. It's also painless and untreatable.
• Blood-sugar issues can affect our vision.

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.
