Fluorescein angiography in carotid disease

Twenty four cases in whom occlusive disease of the carotid artery was proven by digital subtraction angiography or direct carotid arteriography were studied. In five cases venous stasis retinopathy was evident ophthalmoscopically. Fluorescein angiography was abnormal in 19 cases. The abnormalities found were microaneurysms (16 cases); slow arteriovenous transit time (8 cases); macular oedema (8 cases); leakage from the arterioles (3 cases); disc new vessels (4 cases). The differences between this retinopathy and diabetic retinopathy are discussed.
