Transporters are found on the membranes of cells and play a key role in transmitting signals between cells. In Ocular Transporters in Ophthalmic Diseases and Drug Delivery, a panel of distinguished authors discusses all the latest developments in the study of ocular transporters. Focusing on the molecular characteristics, localization, and substrate specificities in various compartments of the eye, this volume discusses how transporters regulate the clarity of the cornea and lens, the movements of fluids across the ciliary epithelium and nutrients across the retinal pigment epithelium. It also provides an in-depth look at how mutations or dysfunction of specific transporters can contribute to various disorders in the eye, including blindness, and provides its readers with potential targets and strategies to allow safe passage of therapeutic drugs into the eye.

Focuses on the molecular characteristics, localization, and substrate specificities of several classes of well-known membrane transporters in various compartments of the eye Illustrates how mutations or dysfunction of specific transporters can contribute to various disorders in the eye, including blindness Examines how epithelial and endothelial barriers can block drug delivery and limit ocular availability of drugs Includes supplementary material: sn.pub/extras
