Ocular complications in young adults with insulin-dependent diabetes mellitus since childhood.
A cross-sectional study in 80 insulin-dependent diabetic patients born 1963-1968 who experienced the onset of diabetes before 15 years of age showed that at a mean age of 21.6 (range 17-25) years and after a mean duration of diabetes of 13.3 (range 6-24) years, 80% of the patients had retinopathy: 70% had background and 10% proliferative changes. Retinopathy correlated with the duration of the diabetes and poor glucose control at 15 years of age but not with the actual level of glycated haemoglobin. The severity of retinopathy was worse in women than in men. One patient (1.2%) was blind. Two patients had had cataract operations and 66% had myopic refraction in one or both eyes. In 61 patients a further period of ophthalmological follow-up of 3-4 years was included. After 20 years of diabetes, all had retinopathy and 29% had proliferative changes: 33% had received laser treatment after 8-27 (mean 16.1) years of diabetes. Altogether, 2 patients (2.5% of the original series) were blind. For prevention of diabetic retinopathy and blindness, good glucose control from puberty and careful ophthalmological follow-up after transfer of the patient from paediatric to adult diabetes care play major roles.
