The Department of Ophthalmology, Asahikawa Medical University, has been engaged in research and development of telemedicine systems to observe affected parts in three dimensions since 1998. We currently use a telemedicine system composed of commercially available high-definition (HD) pictures device. We can use the technology to transmit ultra-high-definition (UHD) pictures of the region of interest (ROI) among doctors preferentially and in high quality. We intend to exert our efforts to obtain higher-resolution transmitted pictures while exploring ways to minimize the financial burden of affiliated hospitals.
