The Vertical and Horizontal Pathways in the Monkey Retina Are Modulated by Typical and Atypical Cannabinoid Receptors

Cells, 2021
The endocannabinoid (eCB) system has been found in all visual parts of the central ner-vous system and plays a role in the processing of visual information in many species, including monkeys and humans. Using anatomical methods, cannabinoid receptors are

Dietary Supplementation of Antioxidant Compounds Prevents Light-Induced Retinal Damage in a Rat Model

Biomedicines, 2021
Light-induced retinal damage (LD) is characterized by the accumulation of reactive oxygen species leading to oxidative stress and photoreceptor cell death. The use of natural antioxidants has emerged as promising approach for the prevention of LD.

Time Course of Structural, Functional, Complement Changes and Inflammatory Processes in a Sodium Iodate Rat Model of Geographic Atrophy. [PDF]

FASEB J
A sodium iodate (NaIO3)‐induced geographic atrophy (GA) model in pigmented rats was established using in vivo and histological analyses. Morphological, ultrastructural changes, complement and inflammatory processes were evaluated at pre‐dose and 3, 7, and 14 days post‐NaIO3 injection.

Lack of the Sodium-Driven Chloride Bicarbonate Exchanger NCBE Impairs Visual Function in the Mouse Retina [PDF]

, 2012
Regulation of ion and pH homeostasis is essential for normal neuronal function. The sodium-driven chloride bicarbonate exchanger NCBE (Slc4a10), a member of the SLC4 family of bicarbonate transporters, uses the transmembrane gradient of sodium to drive ...

Electroretinography (A Review)

Folia Veterinaria, 2016
Electroretinography (ERG) is a functional test of the outer retina. During an examination, the retina is selectively stimulated. The stimulation of the retina produces a response of the individual retinal cells and reveals information about its function.
