In a population-based cross-sectional study of insulin-dependent diabe
tes mellitus, 42 children - with a median age of 11 years (range 7-15
years) and a median duration of diabetes of 4 years (range 1-12 years)
- underwent an ophthalmological and a biochemical examination (HbA1c)
. None of the children had visual loss due to diabetes, and only 4.8%
had mild, non-proliferative retinopathy. Using cycloplegic refractioni
ng, we found low degree myopia (less than -2D) in 12% of the patients,
whereas non-mydriatic measurements increased the frequency of myopia
to 29%. We therefore recommend the use of cycloplegia in refractive ev
aluations of diabetic children.
