Autoantibodies against retinal proteins in paraneoplastic and autoimmune retinopathy [PDF]
, 2004 BACKGROUND: Autoimmune retinal degeneration may occur in patients who present with sudden or, less commonly, subacute loss of vision of retinal origin, associated with an abnormal ERG, through the action of autoantibodies against retinal proteins.

Uptake and metabolism of retinol (vitamin A) in the isolated perfused rat liver
Journal of Lipid Research, 1965 The isolated perfused liver was employed to study various aspects of retinol-C14 metabolism. The rate of uptake of retinol, retinal, retinoic acid, and retinol acetate was rapid (first-order rate constant, k = 0.12–0.16 min−1) during the first 3–10 min ...

A Dark and Bright Channel Prior Guided Deep Network for Retinal Image Quality Assessment [PDF]
arXiv, 2020 Retinal image quality assessment is an essential task in the diagnosis of retinal diseases. Recently, there are emerging deep models to grade quality of retinal images. Current state-of-the-arts either directly transfer classification networks originally designed for natural images to quality classification of retinal images or introduce extra image ...

Age and diabetes related changes of the retinal capillaries: an ultrastructural and immunohistochemical study [PDF]
, 2015 Normal human aging and diabetes are associated with a gradual decrease of cerebral flow in the brain with changes in vascular architecture. Thickening of the capillary basement membrane and microvascular fibrosis are evident in the central nervous system

Müller cell activation, proliferation and migration following laser injury. [PDF]
, 2009 PurposeMüller cells are well known for their critical role in normal retinal structure and function, but their reaction to retinal injury and subsequent role in retinal remodeling is less well characterized. In this study we used a mouse model of retinal
