Selective Destruction of the Pigmented Epithelium in the Ciliary Body of the Eye
Science, 1974Perfusion of the internal carotid artery with hypertonic solution selectively destroys most of the pigmented epithelium of the ciliary body of the monkey eye, converts fenestrated endothelium of capillaries to continuous endothelium, and transiently breaks down the blood-aqueous barrier.

Primary adenocarcinoma of pigmented ciliary epithelium in a phthisical eye
Survey of Ophthalmology, 2016We report a case of adenocarcinoma of the pigmented ciliary epithelium arising in a phthisical eye. A 92-year-old man who initially presented with severe ocular pain had calcification extending from the posterior pole to ciliary body on B-scan ultrasonography to a degree not previously reported.

Malignant tumor of the retinal pigment epithelium with extraocular extension in a phthisical eye [PDF]
Graefe's Archive for Clinical and Experimental Ophthalmology, 1996 Malignant tumors of the retinal pigment epithelium (RPE) are exceedingly rare. We describe the histopathologic and immunohistochemical features of a RPE neoplasm that was found accidentally in a blind and painful phthisical eye.The enucleated eye was investigated by light microscopy, and tumor tissue was also studied by electron microscopy ...

1989
Publisher Summary This chapter describes the evidence for epithelium–capillary interactions where the two are apposed, emphasizing structural and functional manifestations such as capillary permeability and cell polarity. The observations derived from human ocular histopathology and experimental animal models are focused in which interactions are ...

Experimental eye enlargement in mature animals changes the retinal pigment epithelium
Visual Neuroscience, 1999Form deprivation has been shown to result in myopia in a number of species such that the eye enlarges if one eye is permanently closed at the time of eye opening. In the quokka wallaby, the eye grows slowly throughout life. After form deprivation, the eye enlarges by 1–1.5 years of age to the size of that in a 4–6-year-old animal and the number ...

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

Temporally controlled targeted somatic mutagenesis in mouse eye pigment epithelium
genesis, 2012AbstractTo generate temporally controlled site‐specific somatic mutations in the mouse eye pigment epithelium, we generated a TRP1‐Cre‐ERT2 transgenic mouse line that expresses the tamoxifen‐dependent Cre‐ERT2 recombinase under the control of the tyrosinase‐related protein 1 (TRP1) promoter.

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.
