Transient or persistent loss of vision in one eye is a common and distinctive manifestation of occlusive vascular disease. Occasionally, both eyes are involved together or sequentially, with temporary or even permanent blindness. The internal carotid arteries supply blood to the organ of vision; therefore pathologies of those arteries caused by arteriosclerosis may have a direct influence on its functioning. The most common syndromes are temporary (amaurosis fugax) or constant reduction of visual acuity. In fundus examination central retinal artery occlusion and branch retinal artery occlusion are the most common diagnosis, while retinal vein occlusion, anterior ischemic optic neuropathy, ocular ischemic syndrome are less common. There are many clinical ophtlamological manifestations due to vascular brain damage. Proper recognition and diagnosis of the disease may protect the patient against serious life-threatening complications such as stroke.
单眼视力短暂或持续丧失是闭塞性血管疾病常见且独特的表现。偶尔,双眼会同时或相继受累,导致暂时甚至永久性失明。颈内动脉为视觉器官供血;因此,由动脉硬化引起的这些动脉病变可能会直接影响其功能。最常见的综合征是视力暂时下降(一过性黑矇)或持续下降。在眼底检查中,视网膜中央动脉阻塞和视网膜分支动脉阻塞是最常见的诊断,而视网膜静脉阻塞、前部缺血性视神经病变、眼部缺血综合征则较少见。由于脑血管损伤会出现许多临床眼科表现。正确识别和诊断该疾病可使患者预防中风等严重危及生命的并发症。
