This book focuses on the physiology and molecular biology of the front and back regions of the eye. Specifically, the chapters of this book cover topics that explain currently less understood aspects of retinal health as well as the use of zebrafish models to understand the molecular pathogenesis of associated diseases. This includes retinitis pigmentosa, diabetic retinopathy ciliopathies in the eye, rhodopsin trafficking and associated disorders, and the biochemistry of cone defects. This book serves as a useful reference for scientists and graduate students seeking to understand protein trafficking mechanisms and metabolic control in retinal diseases.
