In ocular ischemic syndrome, the ischemic condition is due to markedly reduced blood flow and increased vascular resistance of retrobulbar circulation, as in the central retina and posterior ciliary arteries. Chronic hypoxia affects even the iris and ciliary body. The hypoperfusion of the ciliary body leads to a relative hypotony, presumably related to decreased aqueous humor production. Histopathologic study has demonstrated ciliary body atrophy on an ischemic basis. The authors used ultrasound biomicroscopy to demonstrate in vivo the hypotrophic condition of the ciliary body in ocular ischemic syndrome.
在眼部缺血综合征中，缺血状况是由于球后循环（如视网膜中央动脉和睫状后动脉）的血流量显著减少和血管阻力增加所致。慢性缺氧甚至会影响虹膜和睫状体。睫状体灌注不足会导致相对低眼压，这可能与房水生成减少有关。组织病理学研究已证实睫状体存在缺血性萎缩。作者使用超声生物显微镜在活体上证实了眼部缺血综合征中睫状体的萎缩状况。
