在对松鼠猴的一只眼睛的睫状后动脉进行实验性闭塞后，视网膜色素上皮萎缩发生在地理斑块中，但大部分视网膜区域，特别是在视乳头周围区域，仍然正常。视神经乳头仅出现微小区域的萎缩，可能是由于软脑膜和视网膜血管的吻合连接提供了保护。假设猴子和人类的循环动力学相似，缺血性乳头炎必然代表的不仅仅是睫状后动脉的疾病。在青光眼拔罐中，眼压可能通过毛细血管或静脉压迫影响循环，但人们过分强调了睫状后短动脉为视盘供血的事实，并且错误地认为视盘血流的反应可以通过脉络膜循环的研究来预测。
After experimental occlusion of the posterior ciliary arteries in one eye of squirrel monkeys, retinal pigment epithelial atrophy occurred in geographic patches, but much of the retinal area, especially in the peripapillary region, remained normal. Only minute areas of atrophy occurred in the optic nerve head, presumably because of protection afforded by anastomotic connection to the vessels of the pia mater and retina. Assuming that circulatory dynamics of monkeys and humans are similar, ischemic papillitis must represent disease of more than just the posterior ciliary arteries. In glaucomatous cupping, intraocular pressure may affect circulation by capillary or venous compression, but there has been undue emphasis on the fact that the short posterior ciliary arteries supply the disc, as well as unwarranted assumptions that the responses of the optic disc blood flow can be predicted from studies of choroidal circulation.
