Abstract:
Ocular anatomy and physiology is very unique which is why it creates a challenge in developing drugs given by ocular routes. The Eye has several layers of tissues in it. This route is extremely effective due to its rapid onset of action and small dose requirement. Transcorneal penetration is the route of absorption ofdrug.Several different dosage forms are being developed e.g nanoparticles, liposomes, nanomicelles and microemulsion to overcome difficul ties in drug delivery by this route. This review focused on ocular drug delivery has become the standard in modern pharmaceutical design and several possible routes of drug delivery into the ocular tissues
