Purpose:To evaluate the usefulness of computer-assisted diagnosis system from fundus photographs. Material and Method:Color fundus photography was made on 278 eyes with a 45-degree digitalized fundus camera. The series comprised 223 healthy eyes and 55 eyes of simple diabetic retinopathy. The eyes were photographed in the primary position. The fundus photographs were then subjected to a computerized screening program that evaluates bright and dark fundus lesions respectively. Results:For bright lesions,the sensitivity was 99.9% and the specificity was 91.9%. For dark lesions,the sensitivity was 92.4% and the specificity was 73.1%. For detection of both bright and dark lesions,the sensitivity was 94.5% and the specificity was 89.2%. Conclusion:The present system has shown a high precision in evaluating normal and pathological fundus photographs. It promises to be of value in health-screening program.
