Abstract
Purpose:
This study was performed to investigate the causes of recurrent amaurosis fugax in patients without haemodynamically significant carotid stenosis.
Methods:
Pulsatile ocular blood flow (POBF), ocular pulse amplitude (PA) and ocular perfusion pressure (OPP) were recorded for 15 patients and 15 age-matched controls.
Results:
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).
Conclusion:
The results of this study suggest that for some patients with recurrent amaurosis fugax, their symptoms may occur secondary to ocular small vessel disease.
