Recurrent amaurosis fugax without haemodynamically significant ipsilateral carotid stenosis

Acta Ophthalmologica Scandinavica
M McKibbin, D Verma


This study was performed to investigate the causes of recurrent amaurosis fugax in patients without haemodynamically significant carotid stenosis. Pulsatile ocular blood flow (POBF), ocular pulse amplitude (PA) and ocular perfusion pressure (OPP) were recorded for 15 patients and 15 age-matched controls. No significant difference in OPP or POBF was found between the two groups. However, the PA was significantly greater in the control group (p=0.01). The results of this study suggest that for some patients with recurrent amaurosis fugax, their symptoms may occur secondary to ocular small vessel disease.
