The role of the retinal pigment epithelium in eye growth regulation and myopia: A review
Visual Neuroscience, 2005Myopia is increasing in prevalence world-wide, nearing epidemic proportions in some populations. This has led to expanded research efforts to understand how ocular growth and refractive errors are regulated. Eye growth is sensitive to visual experience, and is altered by both form deprivation and optical defocus. In these cases, the primary targets

[Pigment epithelium of the eye in the human embryo in vitro].
TSitologiia i genetika, 1985A model is developed and described for studying cytological differentiation of pigment epithelium cells of the human eye in vitro. It is shown that the differentiation pattern depends on the stage of embryogenesis.

Transport in Eye Epithelia: Ciliary Epithelium and Retina Pigment Epithelium
1978The ciliary epithelium and the retina pigment epithelium constitute the main sites of the blood-ocular barrier and their functions are the restriction of permeability and the secretion of electrolytes and nonelectrolytes, which are of importance for the maintenance of the intraocular pressure in the case of the ciliary epithelium, and the nutrition of ...

Outer Segments of Photoreceptors and the Retinal Pigment Epithelium
Archives of Ophthalmology, 1970The pigment epithelium has two types of processes: (1) relatively slender, fringe-like villi projecting between the outer segments of the photoreceptors, and (2) broad, rampart-like cytoplasmic sheets encompassing the tips of the outer segments.

Proliferating Pigment Epithelium
Archives of Ophthalmology, 1967A snail-like formation of pigment epithelium with interstitial layers of hyalin-like substance was observed in the subretinal fluid of an eye with long-standing secondary detachment. This spiral formation is thought to be formed by the growth of either free-floating daughter cells of proliferated pigment epithelium or a druse that separated from the ...

[Glutathione peroxidase activity of frog eye pigment epithelium].
Biokhimiia (Moscow, Russia), 1981A highly active glutathione peroxidase (80% of which is localized in the water-soluble fraction) was detected in frog eye pigment epithelium tissue. It was shown that more than 75% of the glutathione peroxidase activity of the pigment epithelium tissue is bound to the Se-dependent enzyme.

Biokhimiia (Moscow, Russia), 1980
The induction of lipid peroxidation in the eye pigment epithelium of pigmented rabbits by the Fe2+ + ascorbate and xanthine--xanthine oxidase systems did not result in accumulation of malonic dialdehyde. In albino rabbits the lipid peroxidation of the non-pigmented pigment epithelium and retina occurred at a high rate under the same conditions.

The efficiency of lipid peroxidation inhibition by retinal pigment epithelium of pigmented rabbits is higher than that of albino rabbits. The superoxide dismutase and glutathione peroxidase activities are nearly the same in both tissues; the alpha-tocopherol content is higher in retinal pigment epithelium of albino animals; the oxidation of the pigment
