AbstractType 2 diabetes mellitus (T2DM) is on the rise in children and adolescents. Diabetic retinopathy (DR) is a leading cause of blindness in adult patients with diabetes. However, the exact prevalence of DR and its determinants in pediatric patients with T2DM are unknown. Understanding the burden of DR in pediatric T2DM can help inform screening and management clinical practice guidelines. This systematic review and meta-analysis aimed to determine the prevalence and determinants of DR in pediatric T2DM. The main outcome was the pooled prevalence of DR in pediatric T2DM. Other important outcomes included the assessment of the impact of diabetes duration, method of retinopathy diagnosis, sex, race, and obesity on prevalence. We searched MEDLINE, Embase, CINAHL, Cochrane Library, Web of Science, and the grey literature from inception until April 4, 2021 for relevant data. No language restrictions were applied, and searches were limited to human studies. Two reviewers independently screened for studies of T2DM patients diagnosed <21 years of age with observational study design and ≥10 participants. Risk of bias evaluation was performed and level of evidence analysis was conducted using the Oxford Centre for Evidence-Based Medicine criteria. A random-effects meta-analysis was used to pool the results. Out of 1849 screened studies, 24 studies met the inclusion criteria. The overall prevalence of DR in pediatric T2DM was 6.58% (95%CI 3.46-10.46, I 2 =96%,n=9026). Most cases were classified as minimal or mild non-proliferative DR. Six cases were sight-threatening. Prevalence was higher in studies using fundoscopy than fundus photography to evaluate DR (0.47% [95%CI 0. 00-3.30, I 2 =0%,n=135] vs. 18.20% [95%CI 7.92-31.28, I 2 =89%,n=718]), suggesting that fundus photography was more sensitive in detecting DR than fundoscopy. The risk of DR rose progressively post-diagnosis; while1.25% (95%CI 0. 00-4. 01, I 2 =13%,n=213) of patients had DR <3 years post T2DM diagnosis, this figure rose to33. 03% (95%CI 25.79-40.66, I 2 =0%,n=162) >5 years after diagnosis. Obesity and sex did not impact DR prevalence. White/Middle Eastern patients had a DR prevalence of 7.43% (95%CI 0. 00-31.37; I 2 =97%,P <0. 001, n=4419),while Asians had a higher prevalence of 14.85% (95%CI 0.91-39.16; I 2 =93%,P <0. 001, n=501). In conclusion, DR is a frequent complication in children and adolescents in the early years post T2DM diagnosis. Screening for DR at diagnosis and annually thereafter using fundus photography is critical to allow early detection and management to prevent visual impairment in these patients.Presentation: No date and time listed
