- Abstract: Topical ocular medication is commonly used for eye diseases treatment.In view of low bioavailability and poor efficacy of traditional ocular preparations, the development of novel ocular drug delivery systems has become a great challenge in pharmaceutics.In recent years, nano preparations have been widely used for ocular drug delivery systems. At present, several nanocarriers, such as polymeric micelles, nanoparticles, nanosuspension, liposomes, emulsion, and dendritic polymers have been developed for ocular drug delivery.There are some other new dosage forms, such as in-situ gelling systems, implants, contact lenses, and microneedles are also under continuous research. The aim of development of these new dosage forms is to improve the drugs' ocular bioavailability and therapeutic effects.In this paper, the development in these areas in recent years are reviewed in order to provide reference for the development of new ocular drug delivery systems.
