We studied 45 IDDM without c-peptide response, duration 7-22 years, without proliferative retinopathy. After 2 months run-in period, they were randomly assigned to: (P) 15 received CSII: (C) 15 received multiple s.c. injections via butterfly 5-6x daily;: (M) 15 received twice daily mixed rapid and long acting insulin. All groups improved blood glucose control in the run-in period (p less than 0.0001). After change of treatment (P) and (M) improved further (p less than 0.01) but (C) was unchanged. GFR was supranormal and decreased in (P) and (M). No regression of retinopathy was shown in any group. One in (P) had transient florid pre-proliferative retinopathy which regressed spontaneously without laser treatment. We conclude that retinal response to strict control is complex. A transient deterioration may been seen.
