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

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]
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
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]
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.
