Observational study shows reduced risk of NAION in IIH patients treated with GLP-1 receptor agonists, suggesting potential benefits of these treatments.
GLP-1 RA utilization among IIH patients was associated with a reduced risk of NAION and optic atrophy. These findings align with the proposed pathway linking GLP-1 RA-induced weight reduction to lower intracranial pressure and papilledema reduction in IIH patients; residual confounding cannot be ruled out, and prospective studies are needed to confirm these associations.
