Dual roles of the retinal pigment epithelium and lens in cavefish eye degeneration [PDF]

open access: greenJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2020
Abstract Astyanax mexicanus consists of two forms, a sighted surface dwelling form (surface fish) and a blind cave‐dwelling form (cavefish). Embryonic eyes are initially formed in cavefish but they are subsequently arrested in growth and degenerate during larval development.

Disk shedding in the absence of a pigment epithelium in the lizard parietal eye

open access: hybridVision Research, 1993
The photoreceptors and pigment epithelia of vertebrate retinas rhythmically synthesize and degrade photosensitive membrane, but the origin of the signal to shed the outer segment tips remains unknown. The parietal eye of lizards contains cone-like photoreceptors but no pigment epithelium.

The other pigment cell: specification and development of the pigmented epithelium of the vertebrate eye [PDF]

open access: bronzePigment Cell Research, 2006
SummaryVertebrate retinal pigment epithelium (RPE) cells are derived from the multipotent optic neuroepithelium, develop in close proximity to the retina, and are indispensible for eye organogenesis and vision. Recent advances in our understanding of RPE development provide evidence for how critical signaling factors operating in dorso‐ventral and ...

The retinal pigment epithelium of the eye regulates the development of scleral cartilage

open access: hybridDevelopmental Biology, 2010
The majority of vertebrate species have a layer of hyaline cartilage within the fibrous sclera giving an extra degree of support to the eyeball. In chicks, this is seen as a cuplike structure throughout the scleral layer. However, the mechanisms that control the development of scleral cartilage are largely unknown.

Setting Eyes on the Retinal Pigment Epithelium [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2018
The neural component of the zebrafish eye derives from a small group of cells known as the eye/retinal field. These cells, positioned in the anterior neural plate, rearrange extensively and generate the optic vesicles (OVs). Each vesicle subsequently folds over itself to form the double-layered optic cup, from which the mature eye derives.

Co occurrance of Macular Telangiectasia type 2 with hemorrhagic polypoidal choroidal vasculopathy and response to anti-vascular endothelial growth factor

open access: yesOman Journal of Ophthalmology, 2023
We report the case of a 57-year-old female patient who presented with defective vision in the right eye due to large hemorrhagic pigment epithelial detachment with subretinal hemorrhage near the arcades with scattered retinal pigment epithelium (RPE ...

Presumed Adenocarcinoma of the Retinal Pigment Epithelium in a Blind Eye With a Staphyloma [PDF]

open access: yesArchives of Ophthalmology, 1998
The retinal pigment epithelium (RPE) can undergo reactive hyperplasia and metaplasia following a variety of ocular insults. However, true neoplasms of the RPE are rare. We report a case of a papillary adenocarcinoma of the RPE arising in the blind staphylomatous right eye of a 79-year-old woman with a long history of bilateral posterior staphylomas who

Type 3 Neovascularization Associated with Retinitis Pigmentosa

open access: yesCase Reports in Ophthalmology, 2017
Purpose: To report a case of type 3 neovascular lesion in a patient with retinitis pigmentosa (RP) complicated by macular edema. Case Report: A 78-year-old man with a long follow-up for RP was referred for painless visual acuity decrease in the right eye.

Profound Re-Organization of Cell Surface Proteome in Equine Retinal Pigment Epithelial Cells in Response to In Vitro Culturing [PDF]

open access: yes, 2012
The purpose of this study was to characterize the cell surface proteome of native compared to cultured equine retinal pigment epithelium (RPE) cells. The RPE plays an essential role in visual function and represents the outer blood-retinal barrier.
