Recurrent amaurosis fugax without haemodynamically significant ipsilateralcarotid stenosis

Purpose: This study was performed to investigate the causes of recurrent am aurosis fugax in patients without haemodynamically significant carotid sten osis, Methods: Pulsatile ocular blood flow (POBF), ocular pulse amplitude (PA) an d 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,vith r ecurrent amaurosis fugax, their symptoms may occur secondary to ocular smal l vessel disease.
