The most common microvascular complication to diabetes is damage to the small vessels of the retina, diabetic retinopathy. Because the population ages and diabetes is more common at higher age, it is important to know how the elderly are affected by diabetic retinopathy. In the research project “Retinal examinations in diabetes” we investigate how many of the elderly has and gets diabetic retinopathy and evaluate how it is possible to optimize the retinal examinations which is the foundation in diabetic eye care to timely detect those who need local eye treatment.
