Idiopathic polypoidal choroidal vasculopathy [PDF]

Vojnosanitetski Pregled, 2012
Background. Idiopathic polypoidal choroidal vasculopathy (IPCV) is uncommon condition. It is considered to be a variant of neovascular age-related macular degeneration, but it can be also found in younger patients. Case report.

Comparison of retinal pigment epithelium cell preparations from the bovine eye [PDF]

Experientia, 1990
Retinal pigment epithelium (RPE) cells were collected from bovine eyes using a new method. The cells were harvested by vortexing the RPE and underlying choroid in 0.05 M citrate phosphate buffer, pH 5. RPE cells recovered by this method were compared to a standard method by microscopic examination of cell integrity, estimation of total protein, and ...

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

Pigment 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 ...

Antioxidant Defenses in the Human Eye: A Focus on Metallothioneins

Antioxidants, 2021
The human eye, the highly specialized organ of vision, is greatly influenced by oxidants of endogenous and exogenous origin. Oxidative stress affects all structures of the human eye with special emphasis on the ocular surface, the lens, the retina and ...

No association between cataract surgery and mitochondrial DNA damage with age-related macular degeneration in human donor eyes.

PLoS ONE, 2021
PurposeTo determine whether age-related macular degeneration (AMD) severity or the frequency of retinal pigment epithelium mitochondrial DNA lesions differ in human donor eyes that have undergone cataract surgery compared to phakic eyes.MethodsEyes from ...

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

Oman 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 ...

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

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2019
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.

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

, 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.
