Sonographic patterns for the Doppler ophthalmic test (DOT) were determined
by reviewing the type of graphic record obtained from 25 patients who had
undergone angiography. Three principal patterns were identified, depending
upon whether there was augmentation (Type 1), diminution (Type 2) or no
change (Type 3) in the character of the supraorbital Doppler signal upon
temporal artery compression. Type 1 records were seen in 28 of 33 instances
where the carotid arteries remained patent. Type 2 records occurred in 10
of 14 instances where there was significant carotid stenoses or tortuosity
and in two instances in a patient with a subclavian steal syndrome. A
"false- positive" test was recorded in one instance in a patient with
vascular headaches. There were three Type 3 records.
