NCT03939351

Brief Summary

The purpose of this study is to describe the changes in morphology and Retinal vascularization after revascularization of the internal carotid artery. Indeed, the stenosis of the internal carotid artery can lead to ophthalmological charts. The underlying hypothesis is that revascularization of the internal carotid artery would improve ipsilateral and retinal homolateral perfusion in the short term. The OCT-angiography technique accurately studies the retinal vasculature and also assesses the risk of retinal and choroidal embolism, which is recognized as increased in cases of symptomatic or asymptomatic carotid stenosis.

Study Population

The study will be proposed to patients for whom revascularization has been performed by vascular surgeons (symptomatic, asymptomatic carotid stenosis)

You may qualify if:

  • Patient aged 18 or over
  • Indication of treatment with a carotid revascularization procedure (conventional surgery or angioplasty and stent)
  • Acceptance to participate in the protocol

You may not qualify if:

  • Associated retinal ophthalmological pathology: diabetic retinopathy, age-related macular degeneration, retinal vein occlusion, CRSC (Central serous chorioretinopathy)
  • Refusal to participate in the study
  • Not affiliated to a social security scheme
