Introduction: Current ISPAD guidelines recommend biennial diabetic retinopathy (DR) screening starting at age 11 yrs with type 1 diabetes (T1D) duration 2-5 yrs. Growing evidence suggesting less frequent screening.

Methods: DR was ETDRS graded and progress assed by Markov chain model analysis. Retinal photos were from 2,169 patients (baseline (mean±SD): age 13.1±2.1 yrs, HbA1c 8.5±1.4%, 5.4±2.9 yrs T1D, follow-up 5.3±3.6 yrs) who attended the T1D clinic at least twice in 1990-2018.

Results: In 11/2,169 patients DR progressed to severe non-proliferative (SNP) DR or above. See tables 1 and 2 below for detailed results.

Conclusions: Our data support less frequent DR screening in T1D youth without any DR. Although DR progression is generally slow, poor glycaemic control greatly accelerates it.
