Conjunctival capillaries in the monkey were observed in histological sections to organize approximately parallel and close to the basement membrane of the epithelium, while larger vessels including the lymphatics were disposed deeper in the stroma. This peculiar vascular organization was evident in the palpebral but not in the bulbar conjunctiva. The trilaminar relationship that existed between the conjunctival epithelium, the elastic lamina previously described [1] and the capillaries is discussed. It was argued that such subepithelial capillary organization enhances the exchange of nutrients and gases between the cornea and the conjunctival vessels across the palpebral conjunctival epithelium when the lids are shut during sleep.
在组织学切片中观察到，猴子结膜毛细血管大致平行排列且靠近上皮基底膜，而包括淋巴管在内的较大血管则位于基质更深层。这种特殊的血管组织在睑结膜中明显，而在球结膜中不明显。本文讨论了结膜上皮、先前描述的弹性膜[1]和毛细血管之间存在的三层关系。有人认为，当睡眠时眼睑闭合，这种上皮下毛细血管组织可增强角膜与睑结膜血管之间通过睑结膜上皮进行的营养物质和气体交换。
