  • Look Inside

Funduscopy under compression of the eyeglobe, or digital ophthalmodynamometry, was used in detecting pathological decrease in the pressure of central retinal artery. Further detailed examinations in suspected cases led to the detection of stenosis or occlusion of the internal carotid artery in 8 eyes of 5 patients. By digital subtraction angiography (DSA) , the internal carotid artery showed stenosis by 60% or more in these cases. Fluorescein angiography showed prolonged arteriovenous transit time in cases with stenosis by more than 90%. Electroretinogram showed decreased amplitudes in oscillatory potentials in cases with stenosis by more than 99%. The findings show the value of digital ophthlamometry as a screening procedure for stenosis of internal carotid artery. Fluorescein angiography and electroretinogram are also useful in cases with pronounced stenosis even in apparently normal fundus appearance.
