Two patients with orbital vascular malformation ipsilateral facial nevus flammeus were studied. The literature contains one similar case that interestingly shares with our cases the lack of leptomeningeal angiomatosis. Orbitofacial angiomatosis seems to be a distinct entity from meningofacial angiomatosis because of its true vascular malformation of the orbit.
In a prospective evaluation of 39 patients who had arteriography for suspected carotid stenosis, suction ophthalmodynamometry correctly identified 86% of the patients who had radiographically demonstrable unilateral or asymmetric obstructions. This compares favorably with carotid compression tonography, oculoplethysmography, and Doppler flow studies. The false-positive rate was 27%, a figure higher than the latter two noninvasive tests.
