简要总结
The investigators plan to collect 30 participants with internal carotid artery stenosis to observed the relationship between the degree of internal carotid artery stenosis and fundus vessels （and blood flow）density before operation, and compared with participants without internal carotid artery stenosis.The fundus blood flow density will be observed after intervention operation in order to see whether the operation is effective to improve the density of fundus vessels and blood flow or not.
