此病多见于45岁以上患有高血压动脉硬化或其他心血管病者。起病突然。眼部症状有如下特点: 1.眼底视乳头苍白性水肿,有时伴有火焰状出血及渗出。水肿可局限于视乳头一侧,最多见于上方;也可累及整个视乳头甚至周围的视网膜。眼底动脉一般变细,可有硬化等高血压视网膜病变。如果存在睫状视网膜动脉,可能看到该血管阻塞。眼底血管荧光造影因后睫状动脉阻塞而显示视乳头着色延迟。发病1～数周后,视乳头开始萎缩,多为原发性。 The disease more common in people over the age of 45 suffering from atherosclerosis or other cardiovascular disease. Sudden onset. Ocular symptoms have the following characteristics: 1. Ocular papillets pale edema, sometimes accompanied by flaming bleeding and exudation. Edema can be confined to the side of the optic nerve, most seen above; can also affect the entire optic nerve or even around the retina. Fundus arteries generally thinner, may have hypertensive retinopathy and other sclerosis. If there is a ciliary retinal artery, it may be seen that the blood vessel is occluded. Fundus fluorescein angiography showed clot delay due to occlusion of the ciliary artery. 1 to several weeks after onset, the optic nerve began to shrink, mostly for primary.
