Ocular pulse amplitude in a case of innominate steal syndrome.
OBJECTIVE
To report an inter-eye difference of the ocular pulse amplitude (OPA) in a case of innominate steal syndrome, as measured by recording applanation tonometry.


METHODS
OPA was measured in a 49-year-old male before and after percutaneous transluminal angioplasty of the innominate artery.


RESULTS
Before dilation of the stenotic innominate artery, OPA was 2.00 (+/- 0.49) mm Hg in the right and 3.46 (+/- 0.53) mm Hg in the left eye. After dilation, OPA was 3.26 (+/- 0.51) mm Hg in the right eye and 3.25 (+/- 0.99) mm Hg in the left eye.


CONCLUSIONS
Recording applanation tonometry may be useful for identifying occlusive disease of extracranial vessels in an office setting.
