Ala‐Kauhaluoma M, Koskinen SM, Silvennoinen H, et al. - Researchers conducted the study for comparing subfoveal choroidal thickness (SFCT) and associated clinical variables in patients with carotid stenosis (CS) before and 6 months after carotid endarterectomy (CEA). The prospective non‐randomized Helsinki Carotid Endarterectomy Study – Brain and Eye Sub‐sTudy involved 70 patients (81% male, mean age 69 years) and 40 control individuals (77% male, 68 years), from March 2015 to December 2018. At baseline, patients had thinner mean SFCT than control individuals in both eyes (ipsilateral, 222 vs 257 μm and contralateral, 217 vs 258 μm). Subfoveal choroidal thickness (SFCT) is thinner in CS patients without SFCT and CS grade association. Unchanged SFCT after CEA indicates that choroidal vessels in severe CS are unable to respond to increased blood flow. Bilaterally thin SFCT might be considered as yet another sign of CS.
