David Sinclair alleges GLP-1 drugs linked to a rise in eye-stroke blindness

What was said

"Um, it's called NION, which is now twice as more prevalent because of the GLP-1 drugs. Really? It's not well known. Obviously companies don't want to talk about it, but yes, sudden blindness has doubled seemingly because of these meds."

David Sinclair alleges GLP-1 medicines are linked to a reported doubling in sudden blindness from a condition he refers to as “NION”. He describes it as like a stroke in the eye, says the second eye can also be affected, and adds that correlation does not equal causation while citing Joe Rizzo’s work.
