Exploration: Nanoparticles in the Diagnosis and Treatment of Retinal Diseases

In recent years, research on nanoparticles (NPs) has brought a new phase in the development of medicine. The term “NPs” refers to nanoscale particles, typically between 10 and 1,000 nm in size, that are within the range of cellular and molecular structures. Compared with traditional ophthalmic drugs, NPs can carry drugs to overcome obstacles, target drug delivery, prolong drug release, reduce drug toxicity, and can be used in gene therapy. After a brief introduction to the classification of NPs, we will focus on the potential applications of different NPs in the diagnosis and treatment of different retinal diseases and introduce innovative methods derived from NPs.
