New research suggests a link between semaglutide, a popular weight-loss drug, and an increased risk of NAION. A study in JAMA Ophthalmology found that individuals taking semaglutide had a higher risk of developing NAION compared to those taking other medications. The risk was particularly pronounced within the first year of semaglutide use. While the study doesn't prove causation, the findings raise concerns about potential side effects of this drug. *Not Medical Advice*
