Summary
Carotid endarterectomy benefits patients with ocular symptoms like vision loss. Retro-ocular doppler sonography helps predict good visual outcomes after surgery when ophthalmic artery velocity is optimal.
Area of Science:
- Ophthalmology
- Vascular Surgery
- Neurology
Background:
- Ocular symptoms like amaurosis fugax and scotoma can indicate carotid artery disease.
- Carotid artery stenosis poses a risk for transient ischemic attacks and stroke, potentially affecting vision.
Purpose of the Study:
- To evaluate the ophthalmological outcomes of carotid endarterectomy in patients with ocular symptoms.
- To compare surgical intervention with conservative treatment for such patients.
- To identify predictors of visual prognosis following carotid endarterectomy.
Main Methods:
- Retrospective analysis of two patient groups: 12 undergoing carotid endarterectomy for ocular symptoms and 15 treated conservatively.
- Ophthalmological assessment including fundus examination.
- Retro-ocular doppler sonography to measure ophthalmic artery blood velocity.
Main Results:
- Patients undergoing carotid endarterectomy showed improved ocular outcomes compared to the conservative group.
- Retro-ocular doppler sonography is a valuable tool for vascular assessment.
- Ophthalmic artery blood velocity between 0.2 to 0.4 m/sec predicted a favorable visual prognosis post-surgery.
Conclusions:
- Carotid endarterectomy is a beneficial treatment for selected patients with ocular symptoms secondary to carotid artery disease.
- Retro-ocular doppler sonography can guide treatment decisions and predict visual recovery.
- Optimal ophthalmic artery velocity is a key indicator for successful surgical outcomes.
