ABSTRACT: Objective
To determine if the cumulative incidence of severe retinopathy in patients with type 1 diabetes has changed.Research design and methods
The study looked at 3,781 patients diagnosed with type 1 diabetes (1939-2005), median age at onset 13 (interquartile range [IQR] 9-21) years, and duration of diabetes 19 (IQR 13-27) years. The severe retinopathy was based on a history of laser treatment. Patients were divided into <1975, 1975-1979, 1980-1984, and ?1985 cohorts according to the diagnosis of diabetes.Results
The cumulative incidence of severe retinopathy has declined (P < 0.0001). After 20 years of duration, the cumulative incidence was 23% (95% CI 21-25) and 33 (30-35) in the earliest cohorts, 18 (15-21) in the next cohort, and 6 (4-9) in the recent cohort. After 30 years, the cumulative incidence was 52 and 48% in the earliest cohorts, while it was 62% after 40 years in the earliest cohort.Conclusions
The cumulative incidence of severe retinopathy has declined in patients with type 1 diabetes.
