There are a number of causes of temporary blindness, but most temporary blindness results from sudden temporary changes in blood pressure, such as aortic dissection, basilar artery or retinal migraine, cardiac or carotid emboli, choroidal or retinal vascular spasm, hyperviscosity, severe occlusive carotid disease.
