The integration of digital camera derived images with a computer based diabetes register for use in retinal screening

Exeter district provides a retinal screening service based on a mobile non- mydriatic camera operated by a dedicated retinal screener visiting general practices on a 2-yearly cycle. Digital attachments to eye cameras can now p rovide a cost effective alternative to the use of film in population based eye screening programmes. Whilst the manufacturers of digital cameras provi de a database for the storage of pictures, the images do not as yet interfa ce readily with the rest of the patient's computer held data or allow for a sophisticated grading, reporting and administration system. The system des cribed is a development of the Exeter diabetes register (EXSYST) which can import digitally derived pictures from either Ris-Lite TM and Imagenet TM c amera systems or scanned Polaroids Pictures can be reported by the screener , checked by a consultant ophthalmologist via the hospital network, and a r eport, consisting of colour pictures, map of relevant pathology and referra l recommendations produced. This concise report can be hard copied inexpens ively on a high resolution ink-jet printer to be returned to the patient's general practitioner. Eye images remain available within the hospital diabe tes centre computer network to facilitate shared care. This integrated syst em would Form an ideal platform for the addition of computer based patholog y recognition and total paperless transmission when suitable links to GP su rgeries become available.
