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.
通过回顾25例接受血管造影患者所获得的图形记录类型，确定了多普勒眼科检查（DOT）的超声模式。根据颞动脉压迫时眶上多普勒信号特征是增强（1型）、减弱（2型）还是无变化（3型），确定了三种主要模式。在33例颈动脉保持通畅的病例中，有28例出现1型记录。在14例存在明显颈动脉狭窄或迂曲的病例中，有10例出现2型记录，在1例锁骨下动脉盗血综合征患者中出现2例。1例血管性头痛患者出现1例假阳性检查结果。有3例3型记录。
