Nanozymes for Treating Ocular Diseases

Abstract

AbstractNanozymes, characterized by their nanoscale size and enzyme‐like catalytic activities, exhibit diverse therapeutic potentials, including anti‐oxidative, anti‐inflammatory, anti‐microbial, and anti‐angiogenic effects. These properties make them highly valuable in nanomedicine, particularly ocular therapy, bypassing the need for systemic delivery. Nanozymes show significant promise in tackling multi‐factored ocular diseases, particularly those influenced by oxidation and inflammation, like dry eye disease, and age‐related macular degeneration. Their small size, coupled with their ease of modification and integration into soft materials, facilitates the effective penetration of ocular barriers, thereby enabling targeted or prolonged therapy within the eye. This review is dedicated to exploring ocular diseases that are intricately linked to oxidation and inflammation, shedding light on the role of nanozymes in managing these conditions. Additionally, recent studies elucidating advanced applications of nanozymes in ocular therapeutics, along with their integration with soft materials for disease management, are discussed. Finally, this review outlines directions for future investigations aimed at bridging the gap between nanozyme research and clinical applications.
