Purpose: Digital images and network in the field of ophthalmology enable computer–assisted image analysis and objective investigation of the ophthalmologic examination. Experiences using digital image network and associated research will be introduced to help other researchers who are interested in this kind of work. Methods: Film–based imaging devices such as fundus camera and photo slit lamp were switched to digital photographic systems by attaching digital single lens reflex (SLR) camera and digital video camera. Video system attached to operation microscope and endothelial cell counters were changed to generate digital motion video and digital still image, and record them in digital video 25Mbps (DV25) format, motion picture experts group (MPEG) 2 or 4 format and joint photographic coding experts group (JPEG) format. Analog devices without computer interfaces such as Goldmann perimetry and Lancaster test could be modified by attaching digitizer–integrated computers. Data of closed systems was intercepted through parallel or serial port and converted into text or graphic files. All the data were transferred to medical record server for the data sharing and retrieval. Results: By gathering a multitude of data from various ophthalmologic devices, electronic medical record system (EMR) was successfully developed. Digital fundus photographs and angiographs could be used for the development of the diabetic retinopathy screening program and the retinal perfusion analysis program. Conclusions: Digital image and data network will be a powerful method in the study of ophthalmologic image analysis and clinical works.
