Retinal detachment in retinitis pigmentosa [PDF]

BMJ Open Ophthalmology, 2020
Objective Retinitis pigmentosa-related retinal detachment (RPRD) is rare, and the full spectrum of retinal complications is not well defined. To describe the types of retinal detachment in patients with retinitis pigmentosa and the surgical outcomes of RPRD. Methods

Retinal Organoids and Retinal Prostheses: An Overview

International Journal of Molecular Sciences, 2022
Despite the progress of modern medicine in the last decades, millions of people diagnosed with retinal dystrophies (RDs), such as retinitis pigmentosa, or age-related diseases, such as age-related macular degeneration, are suffering from severe visual impairment or even legal blindness.

Retinal Prosthesis [PDF]

IEEE Transactions on Biomedical Engineering, 2012
Retinal prosthesis has been translated from the laboratory to the clinic over the past two decades. Currently, two devices have regulatory approval for the treatment of retinitis pigmentosa. These devices provide partial sight restoration and patients use this improved vision in their everyday lives.

Analysis of retinal vessels in eyes with retinitis pigmentosa by retinal oximeter [PDF]

Acta Ophthalmologica, 2014
AbstractPurposeTo study changes in the oxygen saturation and calibre of retinal vessels in the eyes of patients with retinitis pigmentosa (RP).MethodIn this cross‐sectional study, 63 eyes of 63 patients with RP and 14 eyes of 14 healthy subjects were enrolled and examined at Toyama University Hospital. Retinal oximetry measurements were performed using

Adult limbal neurosphere cells: a potential autologous cell resource for retinal cell generation [PDF]

, 2014
The Corneal limbus is a readily accessible region at the front of the eye, separating the cornea and sclera. Neural colonies (neurospheres) can be generated from adult corneal limbus in vitro.

Retinal Hemodynamics in Retinitis Pigmentosa

American Journal of Ophthalmology, 1996
To investigate the retinal hemodynamic changes occurring in patients with retinitis pigmentosa (RP).Bidirectional laser Doppler velocimetry and monochromatic fundus photography were used to determine retinal venous diameter (D), maximum erythrocyte velocity (Vmax), and volumetric blood flow (Q) in the major retinal veins of eight patients with RP and ...

Stabilization of the retinal vascular network by reciprocal feedback between blood vessels and astrocytes [PDF]

, 2005
Development of the retinal vasculature is controlled by a hierarchy of interactions among retinal neurons, astrocytes and blood vessels. Retinal neurons release platelet-derived growth factor (PDGFA) to stimulate proliferation of astrocytes, which in ...

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.

Formation and enterohepatic circulation of metabolites ofc retinol and retinoic acid in bile duct-cannulated rats

Journal of Lipid Research, 1966
Four hours after intraportal injection of retinoic acid-14C into bile duct-cannulated rats, less than 10% of the radioactivity was recovered in the liver, intestine, and kidneys. Within 6 hr, 40% of the radioactivity had appeared in bile.
