Pigmented Lesions of the Retinal Pigment Epithelium
Optometry and Vision Science, 2015: The primary eye care practitioner assumes an important role in clinical decisions involving the differentiation between malignant and nonmalignant pigmented lesions. A misdiagnosis may have profound consequences on patient management and visual or life prognosis.

TUMOR-ASSOCIATED RETINAL PIGMENT EPITHELIAL PROLIFERATION SIMULATING RETINAL PIGMENT EPITHELIAL TEAR
Retina, 1989A lesion with both the clinical and fluorescein angiographic appearance of the classical retinal pigment epithelial (RPE) tear was discovered over the dome of an actively growing metastatic choroidal tumor in a patient with a previous history of breast carcinoma. However, our patient exhibited no evidence of pigment epithelial detachment or age-related

Retinitis Pigmentosa Without Pigment
Archives of Ophthalmology, 1969NO treatment is known for the different types of hereditary retinitis pigmentosa although the degenerations have been described with the ophthalmoscope for over 100 years. When bone spicule pigmentation and arteriolar narrowing are visible, most patients have extinguished or very small electroretinograms (ERGs), and histopathologic studies have ...

Retinal pigment epithelium (RPE) arises from neuroectoderm and plays a key role in support of photoreceptor functions. Several degenerative eye diseases, such as macular degeneration or retinitis pigmentosa, are associated with impaired RPE function that may lead to photoreceptor loss and blindness. RPE derived from human embryonic stem (hES) cells can

Acute Retinal Pigment Epitheliitis
American Journal of Ophthalmology, 1997To report a patient with acute retinal pigment epitheliitis examined less than 24 hours after onset of symptoms.One day after the onset of blurred vision in her left eye, a 33-year-old woman had a best-corrected visual acuity of LE, 20/60 -2. The left eye had classic uniform golden-colored nodules in a honeycomb pattern in the foveal retinal pigment ...

Unilateral Retinal Pigment Epithelium Dysgenesis
American Journal of Ophthalmology, 2009To report additional data on a pattern of the fundus described in 2002 as unilateral, idiopathic leopard-spot lesion of the retinal pigment epithelium (RPE).Observational, consecutive case series.The fundus characteristics, natural history, and prognosis of 9 patients are described after examining them by means of diagnostic adjuncts not previously ...

Retinal Pigment Epithelial Window Defect
Archives of Ophthalmology, 1978The clinical and histopathologic features of a solitary retinal pigment epithelial window defect are presented. Fluorescein angiography disclosed an area with early choroidal fluorescence but no late staining. Histopathologic studies showed an intact but attenuated retinal pigment epithelium with partial to complete loss of melanin granules, partial ...

Retinal Pigment Epithelium and Endothelium
Archives of Ophthalmology, 1986To the Editor. —The recent reports on the interactions between retinal pigment epithelium (RPE) and endothelium in vitro point out that an RPElocated inhibitor of neovascularization and an endothelium-located chemoattractant for RPE cells explain only part of the story of how neovascularization and the status quo at Bruch's membrane are controlled.1 ...

Human retinal pigment cell culture
In Vitro, 1983Human retinal pigment epithelium (RPE)-derived cell lines were established from RPE-covered choroid tissue fragments, which had been generated by culture on nontissue culture plastic. Two phenotypes were apparent in a given line: (a) a compact cell which formed domes and ultimately melanosomes before being sloughed; and (b) a squamous cell which was ...
