Answer

The association between chronic hyperglycemia and increased risk of microvascular complications in patients with type 1 DM was demonstrated in the Diabetes Control and Complications Trial (DCCT). [77] In that trial, intensive therapy designed to maintain normal blood glucose levels greatly reduced the development and progression of retinopathy, microalbuminuria, proteinuria, and neuropathy, as assessed over 7 years.

The DCCT ended in 1993. However, the Epidemiology of Diabetes Interventions and Complications Study (EDIC), an observational study that continues to follow the patients previously enrolled in the DCCT, has demonstrated continued benefit from intensive treatment. [78, 79]
