Normal eyes in type 1 diabetics stay normal after one year of treatment with continuous subcutaneous insulin pump

Seven patients with type 1 diabetes mellitus were restored to near normoglycaemia by treatment with continuous subcutaneous insulin infusion pumps (CSII). The patients were examined with ophthalmoscopy, fundus photography and fluorescein angiography before and one year after the start of CSII treatment. In addition, ophthalmoscopy was performed after 6 months of treatment. All 14 eyes were normal prior to the CSII treatment and none had developed any signs of retinopathy after 6 months or 1 year. It is concluded that metabolic control can be near normalized with CSII treatment without any risk for development of diabetic microangiopathy in type 1 diabetics with normal eyes.
