Abstract
Ocular infirmities significantly influence a person’s routine process by impairing vision to the point of blindness. Effective ocular drug administration with significant bioavailability is challenging due to physiology and defensive mechanisms, which is majorly due to inadequate epithelial permeability and quick removal of the drug from the eye after administration. Due to the numerous restrictions on drug distribution across the blood–retinal barrier, conventional medicines cannot provide definitive therapy for all ocular illnesses, making it a significant clinical issue. However, significant breakthroughs in the management of ocular disorders have been made possible by the use of biopolymeric drug transport with nanoscience. The use of biopolymers in ophthalmic medications has produced several positive effects, including safety, prolonged retention times, improved bioavailability, and controlled release via adhesion to epithelia. Moreover, therapeutic implementation of nanostructure materials, from diagnosis to therapy, has also received significant attention. This evolving biopolymer-based nanoscale drug delivery system has enhanced the drug's ability to pass through various ocular barriers with improvement in bioavailability. Among other beneficial characteristics, biodegradable polymers offer amended retention period and extended release. This review emphasizes the various biopolymer-based fabricated nano-formulations used to mitigate ocular infection.
