Vitamin A is a generic term for a group of similar compounds called retinoids. Retinol is the form of vitamin A found in animal-derived foods, and it is converted in the body to

The protective role of taurine in photoreceptor degeneration, retinal ganglion cell loss, and other retinal morphological injuries in in vitro and in vivo disease models shows that it plays an

To report a case of late-onset Stargardt disease, discuss the differential diagnosis, and review the role of vitamin A supplementation in Stargardt disease. Observations . A 60

Recent findings linking mutations in RPE-expressed genes encoding visual cycle proteins to diverse forms of retinal dystrophy and dysfunction have resulted in a new

This chapter presents an overview of the visual cycle, as well as the function of the RPE genes involved in the conversion of vitamin A to 11-cis retinal, the chromophore of the visual pigments.

Vitamin A is the first defined vitamin and is also known as an anti-inflammatory micronutrient.Although the primary biological function is preservation of epithelial tissue

Vitamin A (retinol) is an essential micronutrient with a crucial role in the immune system of non-ruminant animals, such as swine and poultry. It includes three chemical
