The complex anatomy and the existence of multiple barriers in the eye pose a considerable challenge to successful drug delivery.  Therefore, ocular transporters and receptors are important targets for drug delivery. Significant advancements have been made in the field of ocular transport research. In this book, the author describes the cutting edge research being carried out and focuses specifically on the anatomy and physiology of the eye, biology of ocular transporters and receptors, techniques in characterization of transporters and receptors, transporters and receptors in the anterior and posterior segment in the eye, the role of ocular transporters and receptors in drug delivery, and transporter-metabolism interplay in the eye.
