Summary
Cerebrovascular reconstruction for chronic ocular ischemia (COI) significantly improves or stabilizes vision in most patients. This study highlights the link between severe cerebrovascular disease and vision loss in COI patients.
Area of Science:
- Vascular Surgery
- Ophthalmology
- Neurology
Background:
- Chronic ocular ischemia (COI) is a serious condition affecting vision.
- Extracranial cerebrovascular disease can lead to COI.
- Understanding COI demographics and outcomes is crucial for treatment.
Purpose of the Study:
- To investigate the demographics, presentation, and outcomes of patients with COI undergoing cerebrovascular reconstruction.
- To identify associations between cerebrovascular disease severity and symptomatic eyes.
Main Methods:
- Retrospective review of 17 patients with COI undergoing cerebrovascular reconstruction over 9 years.
- Analysis of patient demographics, ocular symptoms, and cerebrovascular disease extent.
- Correlation of visual acuity changes with surgical outcomes.
Main Results:
- Seventeen patients (3% of all cerebrovascular reconstructions) presented with COI.
- Ninety-five percent of symptomatic eyes experienced rapidly declining visual acuity.
- Worse ipsilateral internal carotid artery, external carotid artery, aortic arch branch, and vertebral artery disease were significantly associated with symptomatic eyes.
- 94% of patients experienced subjective visual improvement or stabilization after revascularization.
Conclusions:
- Significant cerebrovascular disease is often present ipsilateral to symptomatic eyes in COI patients.
- Cerebrovascular reconstruction is an effective treatment for COI, leading to vision improvement or stabilization in the majority of cases.
