Arterial occlusion or stenosis

Carotid artery occlusion or stenosis can lead to inadequate blood supply to the brain and eyes, resulting in a range of brain and eye symptoms. Studies have now shown that this fundus change is not due to venous stasis, but due to carotid artery obstruction or stenosis caused by long-term insufficient perfusion of ophthalmic artery is called hypoperfusion retinopathy. Carotid artery obstruction can also cause anterior ischemia of the eye, which is known as ocular ischemia syndrome along with fundus changes.
