摘要
The eye is a complex organ made up of diversifed cells with specifed functions. Presence of anatomical, physi-ological and physiochemical barriers make it diffcult to deliver drugs in therapeutic amounts at intended sites. To overcome these, drug delivery scientists have fol-lowed two distinct yet complimentary approaches. The frst involves using alternate delivery routes to conven-tional ones allowing for more direct access to intended target sites. Second approach involves development of novel drug delivery systems providing better perme-ability, treatability and controlled release at target site. Combination of both these approaches are being uti-lized and optimized in order to achieve optimal therapy with minimal adverse effects.
