Abstract: Eye is composed of optical part and sensory part, and the sensory retina converts light to electrical neural signal. In the 20th century, many ophthalmic diseases were conquered with the help of pharmaceutical and surgical advancement, and the microsurgery based on the micromachining and microelectronics contributed on this very much. However, in the case of photoreceptor damage, there is no treatment until now. Recent advancement of biotechnology and biomedical engineering gives hope onto this doomed situation. In this talk, advances in the ophthalmic microsurgery/machines and several different biomedical approaches for the restoring vision will be introduced, such as gene transfer, stem cell approach, tissue transplantation and the electrical stimulation of visual system.Bio: Jong-Mo Seo graduated at the Seoul National University (SNU) School of Medicine, took resident course and retina fellowship in Seoul National University Hospital (SNUH) and got his M.S. and Ph.D. degree in biomedical engineering at SNU. He worked as a retina surgeon in SNUH and in the year 2008 moved to the department of Electrical and Computer Engineering (ECE) of SNU as an assistant professor. He also served as a staff for the Electronic Medical Record (EMR) system of SNUH from the 1999 to 2003, designing the computer user interface and developing medical machine-computer data transfer modules. He joined the Seoul Artificial Retina Project from the beginning in the year 2000 and has been working as a moderator and a surgeon for the animal experiment. He is now an associate professor at SNU ECE and co-joined professor at SNUH biomedical research institute and SNU medical school.
