Abstract

Abstract : Purpose . To evaluate the change in choroidal thickness after carotid artery endarterectomy (CEA) in patients without retinal pathology. Methods . A prospective series of patients who underwent CEA at the Tel Aviv Medical Center. Spectral domain optical coherence tomography (SD-OCT) was performed one day before the CEA and at least 6 months after. Data included medical history, smoking history, percentage of carotid stenosis before and after CEA, best-corrected visual acuity (BCVA), central macular thickness (CMT), and choroidal thickness (subfoveal, 500 µ m, 1000 µ m, and 1500 µ m nasal and temporal). Results . Eight patients (seven male and one female) with a mean age of 70.5 ± 6.1 years were included in the study. The mean internal carotid artery (ICA) stenosis was 89.8% ± 5.1 in the operated side, 33.7% ± 10.9 in the nonoperated side (p < 0.0001 ), and 0% after CEA (p < 0.0001 ). Operated side BCVA was 0.35 ± 0.66 compared to 0.61 ± 0.83 in the nonoperated side (p = 0.51 ). The mean subfoveal choroidal thickness (SFChT) of the operated side was 277 ± 67 µ m compared to 268 ± 71 µ m in the nonoperated side (p = 0.81 ). SFChT and CMT after CEA were 275 ± 64 µ m (p = 0.96 ) and 268 ± 29 µ m (p = 0.98 ), respectively. Conclusions . SFChT and CMT in patients without retinal or choroidal pathology and significant ICA stenosis can be normal and may not change after successful ipsilateral CEA.
