| Popis: | INTRODUCTION The corrective effect of carotid endarterectomy (CEA) on impaired ophthalmic artery flow in patients with significant internal carotid artery (ICA) stenosis presenting with ocular ischemic syndrome (ie, symptomatic patients) is well established. However, there is no clear evidence regarding the efficacy of CEA for improvement of neuroretinal function in patients without symptoms of ocular ischemic syndrome. OBJECTIVES We aimed to determine the effects of CEA on retinal function in asymptomatic patients with hemodynamically significant ICA stenosis. PATIENTS AND METHODS We enrolled 46 patients with ICA stenosis referred for CEA. Full-field electroretinogram (ERG), pattern ERG, and pattern visual evoked potentials, as well as optical coherence tomography and ophthalmologic examination of both eyes were performed 1 day before and 3 months after CEA. We analyzed eyes ipsilateral (EIE) and contralateral (ECE) to CEA. RESULTS We observed an increase in several ERG wave parameters in both eye groups, compared with baseline values: rod b-wave amplitudes (P |
