Amayrosis fugax: Amaurosis fugax is transient loss of vision in one eye from circulatory issues. One of the causes is a clot from neck arteries or heart going into the eye through blood stream. There are other causes to be considered like glaucoma , vasculitis(inflammation of blood vessels especially giant cell arteritis) coagulation disorder. If all work up is negative , chance of recurrence is very low.

Anti platelet medication is frequently recommended to reduce small platelet emboli from rough spots in the arterial circulation to the eye and brain

Sometimes it's hard : To find the exact cause. Vascular spasm may cause it but hard to prove. Some autoimmune condition may cause it.

Further imaging: If your husband is truly having amaurosis fugax and if the carotid ultrasound and heart echo are normal, then he needs a ct angiogram of the head, neck, and aortic arch to rule out other potential etiologies, including confirming the carotid arteries are disease free. Carotid ultrasound is a good, but not perfect, test. I'd suggest he see a board certified vascular surgeon to discuss further.

A trams esophageal echocardiogram may be more informative as it may provide better images of the left atrium and appendage., and aortic arch

Agreed. TEEs are more useful than TTEs in this setting in certain cases. Still a CTA best for evaluating calcification of the arch.

Migraine.: If associated with aura, headache and re urgency, this may be a migraine type. Atherosclerosis with irregular plaque in the ascending aorta, as well as carotid plaque can cause embolism, or platelet emboli. Anti platelet therapy may be helpful until or after the source is determined. Some coagulopathies may also cause symptoms.
