    Structural analysis of potential barriers to bulk-flow exchanges between uvea and sclera in eyes of Macaque monkeys (1990)

    Notes: Summary The uveal tract of the eyes of monkeys was examined by electron microscopy using both thin sections and freeze-fracture replicas. The ultrastructural features of the lamina fusca in the monkey resembled those previously described for rabbit. The lamina fusca was composed of numerous interleaved processes of fibroblastic and pigmented cells and contained tight junctions between fibroblastic cell processes that were predominantly discontinuous, as well as numerous fenestrations through the attenuated cell processes. There was no regional compaction of cellular processes traversing the entire uvea at the level of the ora serrata as reported previously in hamster eyes.

    Structural analysis of potential barriers to bulk-flow exchanges between uvea and sclera in eyes of rabbits (1990)

    Notes: Summary The uveal tract of rabbit eyes was examined using transmission electron microscopy of thin sections and freeze-fracture replicas. Emphasis was placed on the organization of pigmented and fibroblastic cells near the ora serrata and more generally in the lamina fusca, since these regions were previously found to restrict ingress of tracer molecules to the choroid in hamster eyes. There were significant differences between rabbit and hamster in the disposition of the pigmented cells and fibroblastic layers, the extent and patterns of tight junctions adjoining fibroblastic cells, and the presence of vesicles or fenestrations in the attenuated fibroblastic cell processes.

    Uveoscleral permeability to intracamerally infused ferritin in eyes of rabbits and monkeys (1992)
    Springer

    Notes: Summary The permeability of the uveoscleral outflow pathway from the anterior ocular chamber was examined in rabbit and monkey eyes using anionic ferritin as a tracer. Ferritin, infused intracamerally, had ready access to the choroidal interstitium, and the degree of penetration was generally correlated with the time and pressure relationships during infusion. In both species, there were accumulations of tracer in intercellular spaces at the lamina fusca, but tracer was also present in the sclera. Thus, in contrast to the situation in the eyes of hamsters, the uveoscleral outflow pathway in the eyes of rabbits and monkeys includes the choroidal connective tissue and allows passage of relatively large molecular weight substances.
