Cover Story: Posterior segment eye diseases pose treatment challenges due to ocular barriers limiting drug penetration, residence time, and bioavailability. Current treatments require frequent dosing, including eye drops or intravitreal injections. Biodegradable nano-based drug delivery systems (DDS) offer a solution by staying in ocular tissues longer, passing through barriers for higher bioavailability, and being composed of biodegradable, nanosized polymers. This review examines DDS in ocular disease treatment, therapeutic challenges in posterior segment diseases, and the enhancement of treatment options through various biodegradable nanocarriers. A literature review from 2017 to 2023 highlights the rapid evolution of nano-based DDSs, promising to overcome current clinical challenges. View this paper
