. The spectrum of diabetic retinopathy, the need for fundus screening and the evaluation of two presumptive screening methods, was investigated in a population based study among patients with type II diabetes. Retinal evaluation was performed in 86.9% of the known diabetic population. Background diabetic retinopathy was detected in 37.8%, pre‐proliferative in 1.1% and proliferative retinopathy in 3.8%. Diabetic maculopathy was found in 24.3% of the patients. Laser therapy was considered in 11.4% of the patients due to diabetic retinopathy, and in 14.6% when venous occlusive diseases were included. Two methods, a slit‐lamp observation enhanced by a 60D lens and reading from two non‐stereo photographs of the posterior pole, were evaluated among 154 patients willing and mentally capable of being examined by either method. The sensitivity of the photographic method was 87/97% (right eye/left eye) when detecting background retinopathy and 81/80% for maculopathy versus 69/61% and 79/63%, respectively, with the slit‐lamp method. The photographic method could be applied in 93% of the patients mentally capable of cooperation. Only 5 or 6 patients could be examined per hour with the 60D slit‐lamp compared with 30–35 examined by reading retinal photographs. The photographic method is recommended as an easy and reliable screening device for diabetic retinopathy among patients with type II diabetes.
