QuestionIs there any evidence for the benefit of routine retinopathy screening in diabetic patients?AnswerStudies and guidelines show that routine diabetic retinopathy screening improves early detection and treatment of diabetic retinopathy. Consistent evidence reveals that early treatment prevents or delays loss of visual acuity and blindness. There is no direct evidence from randomized controlled trials demonstrating the benefit of the screening test, but in view of indirect evidence a randomized controlled trial would be unethical. With respect to the screening interval, further evaluation should be carried out because of limited specificity to avoid possible false positive results, especially in early stages of diabetes mellitus.
