document: Hand-held digital video-camera for eye examination and follow-up We developed a hand-held digital colour video-camera for eye examination in primary care . The device weighed 550 g . It featured a charge-coupled device -LRB- CCD -RRB- and corrective optics . Both colour video and digital still images could be taken . The video-camera was connected to a PC with software for database storage , image processing and telecommunication . We studied 88 normal subjects -LRB- 38 male , 50 female -RRB- , aged 7-62 years . It was not necessary to use mydriatic eye drops for pupillary dilation . Satisfactory digital images of the whole face and the anterior eye were obtained . The optic disc and the central part of the ocular fundus could also be recorded . Image quality of the face and the anterior eye were excellent ; image quality of the optic disc and macula were good enough for tele-ophthalmology . Further studies are needed to evaluate the usefulness of the equipment in different clinical conditions
