Vision is often deemed the most vital sense and the one people fear losing the most. It enables independent functioning and work. The complex eye, prone to various diseases, has distinct anatomical parts affected by local and systemic conditions. Treating eye diseases is intricate due to retinal physiology and eye anatomy. Administering drugs to the eye is challenging due to its unique features. Topical (eye drops) and systemic (tablets) methods are least invasive for drug delivery to the eye.
