Ocular Perfusion in Patients With Unilateral Carotid Artery Stenosis
The aim of the presented study is to evaluate ocular blood flow, respectively optic nerve head blood flow in patients with carotid artery stenosis before and after carotid endarterectomy or carotid artery stenting. Additionally, the investigators aim to compare optic nerve head blood flow in patients with CAS and healthy age- and sex-matched control subjects. Furthermore, the investigators intend to evaluate brain tissue oxygenation in patients with carotid artery stenosis before, during and after CEA and carotid artery stenting. Finally, the investigators will assess potential correlations between LSFG and NIRS results in patients with unilateral carotid artery stenosis.
