Abstract A total of 209 diabetic children and adolescents aged 6–17 years (mean, 12.6 ± 2.3 years) were examined by ophthalmoscopy, video fluorescein angiography and hemoglobin (HbA1c) tests. Microaneurysms were found in 26% of the children (ophthalmoscopy, 11%; angiography, 23%). The prevalence of retinopathy was 16% in patients aged 6–10 years, 27% in those aged 11–13 years and 36% in those aged 14–17 years. Only five diabetics aged 11–17 years showed lesions other than microaneurysms (hard exudates, intraretinal hemorrhages or retinal capillar leakage). Retinal blood flow was quantified using video fluorescein angiography. The arm-retina time (ART) and the arteriovenous passage time (AVP) as parameters of the retinal microcirculation were obtained using an image analysing system. The mean value for ART was 9.7±2.5 s and that for AVP was 1.43±0.52 s. AVP was significantly shorter in diabetic children and adolescents with good glycemic control (HbAlc, 〈7%; AVP, 1.35±0.44 s) than in those with bad glycemic control (HbA1c, ≥ 9 % ; AVP, 1.65 ±0.51 s).
