Abstract:
Of the total population of 270 25- to 34-year-old insulin dependent diabetic patients with onset less than or equal to 30 years in the county of Fyn, Denmark, a sample of 138 was drawn for examination. Of the 138 examined patients, 4 (2.9%) were legally blind and 119 (86.2%) had good vision in both eyes. The cause of reduced vision was proliferative retinopathy in the majority of eyes. Refraction, measured objectively with a refractometer in cycloplegia and transformed to spherical equivalents, was -0.25 D or more myopic in approx. 50% of eyes. Correlation analyses did not demonstrate significant association between refraction, and duration of diabetes or Hb-A1c.
