Oxidative stress due to free radicals is related to the pathogenesis of many chronic disorders including cancer, inflammation, and neurological diseases. Oxidative stress such as aging and light exposure is also considered to be associated with age-related macular degeneration and cataract. The ocular surface is chronically exposed to oxidative stress including ultraviolet light, the oxygen in air, and changes in oxygen pressure due to blinking. We demonstrated that a rat dry eye model with a jogging board showed corneal epithelial disoders and elevated levels of oxidative stress, suggesting that the pathogenesis of epithelial disorders in dry eye with low frequency of blinking is related to oxidative stress. Next, using a model of laser-induced choroidal neovascularization (CNV), we showed that angiotensin receptormediated inflammation is required for the development of CNV. We also demonstrated that mice deficient in superoxide dismutase (SOD) showed typical clinical features of AMD. Finally, we proposed our thoughts about regenerative medicine, that is, to maintain quiescent stem cells, we have to regulate the aging of stem cells.

The ocular drug discovery field has evidenced significant advancement in the past decade. The FDA approvals of Rhopressa, Vyzulta, and Roclatan for glaucoma, Brolucizumab for wet age-related macular degeneration (wet AMD), Luxturna for retinitis pigmentosa, Dextenza (0.4 mg dexamethasone intracanalicular insert) for ocular inflammation, ReSure sealant to seal corneal incisions, and Lifitegrast for dry eye represent some of the major developments in the field of ocular therapeutics. A literature survey also indicates that gene therapy, stem cell therapy, and target discovery through genomic research represent significant promise as potential strategies to achieve tissue repair or regeneration and to attain therapeutic benefits in ocular diseases. Overall, the emergence of new technologies coupled with first-in-class entries in ophthalmology are highly anticipated to restructure and boost the future trends in the field of ophthalmic drug discovery. This perspective focuses on various aspects of ocular drug discovery and the recent advances therein. Recent medicinal chemistry campaigns along with a brief overview of the structure-activity relationships of the diverse chemical classes and developments in ocular drug delivery (ODD) are presented.
