The etiology of monocular ischemia influences the clinical manifestation and long-term neurologic and visual prognosis. During a 10-year period, 140 patients with monocular visual symptoms were evaluated and assigned to a carotid bifurcation occlusive disease group (group I) or a primary ocular disease group (group II) on the basis of angiographic findings and ophthalmologic evaluation. Patients with symptoms secondary to emboli from the carotid bifurcation tended to have a shorter duration of blindness and a lower incidence of permanent blindness initially and during follow-up. The presence of Hollenhorst plaques or retinal artery occlusion did not have any discriminatory diagnostic value since the incidence was similar in both patient groups. Since both primary eye disease and carotid bifurcation occlusive disease can be initially seen as monocular ischemia, carotid angiography and ophthalmologic consultation are necessary to select those patients who will benefit from carotid endarterectomy.
单眼缺血的病因会影响临床表现以及长期的神经和视觉预后。在10年期间，对140例有单眼视觉症状的患者进行了评估，并根据血管造影结果和眼科评估将其分为颈动脉分叉闭塞性疾病组（I组）或原发性眼病组（II组）。继发于颈动脉分叉栓子的症状患者最初及随访期间失明持续时间往往较短，永久性失明发生率较低。Hollenhorst斑块或视网膜动脉阻塞的存在不具有任何鉴别诊断价值，因为两组患者的发生率相似。由于原发性眼病和颈动脉分叉闭塞性疾病最初都可表现为单眼缺血，因此需要进行颈动脉血管造影和眼科会诊，以筛选出能从颈动脉内膜切除术中获益的患者。
