Senses consist of a variety of inputs mediated by the cerebral nerve, spinal cord and internal communication network; and it has been well known that that there are sensory inputs other than the commonly used "five senses".
Eye input is believed to account for a considerably large proportion of these senses. In addition, it is believed that the eyes have also had a great influence on diversification of living organisms.
There are various microstructures to maintain the functions of the eyes. These microstructures undergo physiological deterioration due to aging and other causes. It would be impossible to maintain and improve the quality of life without keeping the normal eye function in super aging society.
There are still a number of refractory ophthalmic diseases without treatment methods, especially retinal diseases. Our laboratory is dealing with research on such ophthalmic diseases, especially development of effective treatment methods. In addition to treatment by cell transplantation and gene therapy, we are especially concentrating on our sustained drug-releasing device that enables local release of medications in the eyes in recent years. This device developed by collaborative research with the Graduate School of Engineering is characterized by its extensible property, which allows sustained release of any drug. Therefore, it can be utilized for a variety of diseases, and we are also carrying out joint research with researchers in other fields.
