Answer

Transient vision loss has been reported to occur after ingestion of a large meal. [6] In this case, visual loss results from hypoperfusion of the eye, as blood is shunted to the mesenteric system. Postprandial visual loss is most common in individuals whose ocular perfusion is already compromised (eg, carotid disease, giant cell arteritis). [6]
