The North Jutland County diabetic retinopathy study

Several population based studies have reported blood glucose levels and blood pressure to be risk factors for the development of proliferative diabetic retinopathy and diabetic maculopathy. Despite their importance, these studies are now dated and may reflect the treatment and population composition of a previous era. Studies of the present diabetic population are therefore in demand. The present study included approximately 1000 patients (65% clinical type I and 35% clinical type II diabetic) undergoing diabetic retinopathy screening and registration of several ophthalmic and non-ophthalmic parameters. The study includes cross-sectional analyses of the prevalence of ophthalmic disorders, and longitudinal incidence studies.
