Community-wide fundus photography was organized for early detection of diabetic retinopathy (DR) by mobile teams. High-quality three-field Kodachrome fundus photography, performed according to the London Protocol through dilated pupils was offered free of charge to primary care; images were taken in the community and assessed centrally. Data are presented from the first 80 primary health care centres (PHCCs) participating, serving 990 000 (about 60 %) of inhabitants in Stockholm County. Beginning in 1990, 6863 diabetes patients were invited by PHCCs; 5490 (80 %) attended. We reached 77 % of persons with known diabetes; only 37 % had had their eyes examined during the preceding 2 years. For 97 % of patients, images were assessable. DR was present in 34 % of patients (non-proliferative DR not requiring further assessment 29 %, non-proliferative DR requiring further assessment 1.1 %, proliferative DR 0.5 % and macular involvement 3.6 %). Re-examination after 2 years was offered to 64 %; follow-up photography after 1 year to 24 %. Fluorescein angiography and/or photocoagulation treatment was performed in 3.6 %. This method of early diagnosis is feasible, acceptable, and reached twice as many patients as did the usual referral-based system of care. We now plan to extend this service to cover the whole county
