Crowded Optic Discs and Risk Stratification of NAION in GLP-1 Receptor Agonist Users: Insights from a Large Multicenter Study

Crowded Optic Discs and Risk Stratification of NAION in GLP-1 Receptor Agonist Users: Insights from a Large Multicenter Study

This large multicenter study reveals that nonarteritic anterior ischemic optic neuropathy (NAION) patients exposed to GLP-1 receptor agonists exhibit similar optic disc crowding compared to nonexposed patients, with smaller cup-to-disc ratios strongly correlating with increased NAION risk.

Semaglutide and Nonarteritic Anterior Ischemic Optic Neuropathy: Synthesizing Evidence from Target Trial Emulations and Global Pharmacovigilance

This review synthesizes recent evidence regarding the association between semaglutide initiation and nonarteritic anterior ischemic optic neuropathy (NAION), contrasting high-risk findings in real-world cohort studies with neutral findings in RCT meta-analyses and exploring potential mechanistic pathways.
