The palisades of Vogt are distinctive normal features of the human corneoscleral limbus. Our clinical studies indicate that they are more discrete in younger and in more heavily pigmented individuals, and that they appear more regular and prominent at the lower limbus than at the upper limbus. They are seen only infrequently in the horizontal meridian. There is some symmetry (though it is not exact) from one eye to the other in the same person. The anatomy of the palisades appears to be unique for a given individual. In this respect, as well as in their microscopic anatomy, the palisades of Vogt appear comparable to fingerprints, and the term "conjunctivoglyphics" ("conjunctival carvings") or "limboglyphics" is suggested in analogy with "dermatoglyphics." The palisades of Vogt have a distinct vasculature with narrow, barely visible, arterial and venous components of radially oriented hairpin loops. Angiography reveals that these vessels leak fluorescein relatively late and only to a moderate extent. They respond to inflammation by dilatation and gross breakdown of their physiologic barrier properties. The functions of the palisades of Vogt are not known with certainty, but their interpalisadal epithelial rete ridges may serve as a repository for corneal epithelial cells. They may thus be important in both aging and diseases of the cornea.
沃格特栅栏是人类角膜缘独特的正常特征。我们的临床研究表明，它们在年轻人和色素沉着较重的个体中更为离散，并且在下角膜缘比上角膜缘看起来更规则、更明显。它们在水平子午线上很少见。同一个人的两只眼睛之间存在一定程度的对称性（尽管并不精确）。沃格特栅栏的解剖结构对于特定个体而言似乎是独一无二的。在这方面，以及在其微观解剖结构上，沃格特栅栏与指纹相似，因此有人建议用“结膜纹”（“结膜刻痕”）或“角膜缘纹”来类比“皮纹”。沃格特栅栏有独特的血管系统，由狭窄的、几乎看不见的、呈放射状发夹环的动脉和静脉成分组成。血管造影显示这些血管相对较晚才渗漏荧光素，且程度适中。它们通过扩张和生理屏障特性的严重破坏来应对炎症。沃格特栅栏的功能尚不确定，但它们之间的上皮嵴可能是角膜上皮细胞的储存库。因此，它们在角膜老化和疾病中可能都很重要。
