But, after getting a CT-scan and seeing a neuro-ophthalmologist, it was revealed he had non-arteritic anterior ischemic optic neuropathy (NAION), a condition in which the loss of blood flow to the optic nerve causes sudden vision loss.
Recent studies have shown an association between drugs such as Ozempic, Mounjaro and Wegovy — which have become phenomenally popular for weight loss — and an increased risk of NAION [.
Of the estimated 15 million Americans now taking such medications for Type 2 diabetes and weight loss, only a relative few have experienced the issue, but for those who have, it’s life-altering.

From my eye researcher friend:
Another thing associated with these drugs is cataract formation. I have a 30-something patient recently who was having trouble seeing at night, not because she couldn't see under low levels of iullumination, but because lit signs were blurry and headlights dazzled her. This began a year after starting tirzepatide. She also had naturally very large pupils.
No one thought to look at her lens because she was so young.
The public is doing a clinical trial on themselves. I'm so glad I haven't had to fight obesity.
