A self-powered artificial retina perception system for image preprocessing based on photovoltaic devices and memristive arrays

Nano Energy, 2020
Artificial retina perception system is significant to pattern recognition and visual function emulation. However, the recent artificial retina system is mainly reported on the integration of three-terminal transistors, whose structural limitations may ...

Retinal microglia – A key player in healthy and diseased retina

Progress in Neurobiology, 2019
HighlightsRetinal microglia contribute to the purposeful and functional histo‐architecture of the developing and adult retina.Robust microglial activation is detrimental to normal functioning of the retina.Retinal microglial activation is a harbinger of ...

The retina

Current Opinion in Neurology, 1996
Prominent amongst last year's diverse papers on the retina were a study of the clinical manifestations of dominant cerebellar ataxia with pigmentary macular dystrophy, a review of the pathogenesis of carcinoma associated retinopathy, the Ischaemic Optic Neuropathy Decompression Trial, and a review of congenital optic disc anomalies.

Cryosurgery of the Retina

International Ophthalmology Clinics, 1976
In 1931, J. Gonin presented his original concept that retinal detachment is caused by a retinal break and reattachment could be achieved by inducing inflammation around the break with diathermy and by simultaneous draining of subretinal fluid. The primary advantage of cryosurgery is the ability to penetrate the sclera and to create a retinal adhesion ...

Proteoglycans in retina

Progress in Retinal and Eye Research, 2002
In this article, we summarize the roles of proteoglycans in retinal tissue. Chondroitin sulfate and heparan sulfate proteoglycans are the major constituents in proteoglycans expressed in retinal tissue. Soluble heparan sulfate proteoglycans are found in the extracellular matrices of the basement membrane, such as the inner limiting membrane and Bruch's

Glia of the human retina

Glia, 2019
The human retina contains three types of glial cells: microglia and two types of macroglia, astrocytes and Müller cells. Macroglia provide homeostatic and metabolic support to photoreceptors and neurons required for neuronal activity. The fovea, the site

Acetylcholine in the retina

Neurochemistry International, 1980
Acetylcholine in the retina is synthesized and released by a sparse group of amacrine cells that symmetrically line both margins of the inner plexiform layer. The action of these neurons is at once very selective (they affect ganglion cells of some functional classes, but not others) and rather diffuse (the dependence of the acetylcholine-sensitive ...

Drugs and the retina

Expert Opinion on Drug Safety, 2004
The retina is relatively protected from systemic drug administration because of the blood-retinal barrier, a highly selective mechanism adapted to providing a regulated homeostatic environment for this highly specialised tissue. However, a number of drugs have been associated with retinal toxicity.
