Sight, or vision, is crucial for human survival. Due to the unique architecture and physiology of the eye, drug delivery scientists and pharmacologists have faced significant difficulties. For the treatment of eye problems, topical administration of both traditional and cutting-edge medication formulations is available. Ophthalmic solutions, suspensions, ointments, gels, and inserts are examples of conventional dosage forms. Microemulsions, nanosuspensions, dendrimers, niosomes, liposomes, etc. are examples of novel dosage forms. Comparing novel drug delivery systems to traditional drug delivery systems, the bioavailability of the medicine is enhanced. The obstacles offered by numerous anterior and posterior segment disorders can be significantly improved, according to recent advancements in the field of ophthalmic drug administration. Here in this article, we are going to discuss the anatomy of the eye, and conventional and novel ophthalmic techniques.
