Vitamin-A metabolism and retinal degeneration

Vitamin A plays an important role in the pathogenesis and during the course of retinal degenerations. Following a brief overview of the metabolic path way of Vitamin A from the entrance into the body to the arrival in retinal target structures, the most important retinal degenerations that are relate d to the Vitamin A-metabolism are presented. Ways of prevention or therapy of such diseases are discussed in the light of the still incomplete knowled ge about basic mechanisms of retinol transport and metabolism.
