The Relationship Between Carotid Artery Stenosis and the Development of Open-Angle Glaucoma: A Long-term Cohort Study in Taiwan.

No statistically significant differences in OAG risk were observed between patients with CAS and the control cohort. The severity of CAS appears to influence OAG risk, with surgical intervention potentially offering protective effects, particularly in patients with mild CAS stenosis (<50%), suggesting that enhanced ocular perfusion post-surgery may act as a protective factor against OAG development.
