Although it is generally thought that lymphatics do not exist in the choroid, there is mounting evidence that lymphatic-like structures do exist in primates and fowl.
METHODS/RESULTS: Our comparison of the ultrastructure of chick and rabbit outer choroid indicates that major differences exist in the non-vascular areas of the choroid: notably, the chick has large lymphatic sinusoids, whereas the rabbit only has a system of large vacuoles contained within the processes of individual fibroblasts.
These results raise questions regarding the similarities or otherwise between species of the management of retinal metabolites, excess tissue fluid and choroidal homeostasis, especially during conditions of overload.
尽管人们普遍认为脉络膜中不存在淋巴管，但越来越多的证据表明，灵长类动物和禽类中确实存在类似淋巴管的结构。
方法/结果：我们对鸡和兔脉络膜外层超微结构的比较表明，脉络膜的非血管区域存在重大差异：值得注意的是，鸡有大的淋巴血窦，而兔只有单个成纤维细胞突起内包含的大液泡系统。
这些结果引发了关于不同物种在视网膜代谢物、多余组织液管理以及脉络膜内环境稳定方面的异同问题，尤其是在负荷过重的情况下。
