OBJECTIVE: To examine the prospective association of retinal vascular fractal dimension with diabetic retinopathy risk in young people with type 1 diabetes. RESEARCH DESIGN AND METHODS: This was a hospital-based prospective study of 590 patients aged 12-20 years with type 1 diabetes free of retinopathy at baseline. All patients had seven-field retinal photographs taken of both eyes. Incident retinopathy was ascertained from retinal photographs taken at follow-up visits.

RESULTS: Over a mean +/- SD follow-up period of 2.9 +/- 2.0 years, 262 participants developed mild non..View full abstract
