Summary
Moyamoya disease can cause serious visual disturbances due to posterior circulation blockages, especially in younger patients. Surgical revascularization, including STA-MCA anastomosis and omentum transplantation, often improves vision.
Area of Science:
- Neurology
- Ophthalmology
- Vascular Surgery
Background:
- Moyamoya disease is a rare cerebrovascular disorder characterized by progressive stenosis of the internal carotid arteries and their branches.
- Visual disturbances are a significant manifestation, often linked to occlusive lesions in the posterior circulation.
Purpose of the Study:
- To evaluate the spectrum of visual disturbances in moyamoya disease.
- To assess the efficacy of surgical revascularization in managing these visual symptoms.
Main Methods:
- Retrospective analysis of 178 moyamoya disease cases, focusing on 43 with visual symptoms.
- Evaluation of surgical interventions including STA-MCA anastomosis with EMS and omentum transplantation to the occipital lobe.
Main Results:
- Visual symptoms like visual field defects and decreased acuity were common, particularly in juvenile-onset moyamoya disease.
- Most patients experienced visual improvement after STA-MCA anastomosis.
- Five cases required direct revascularization via omentum transplantation for persistent visual issues.
Conclusions:
- Posterior circulation occlusive lesions are a primary cause of visual disturbances in moyamoya disease.
- Surgical revascularization is effective in improving visual outcomes.
- Juvenile onset moyamoya disease presents a higher risk for visual complications.
