Implication

Prospective cohort study shows retinal layer thinning linked to glycemic control in youth with type 1 diabetes, indicating potential pathways for diabetic eye disease.

Key Points

To assess the relationship between retinal layer thickness and glycemic outcomes in youth with type 1 diabetes.
Conducted at a pediatric diabetes center
Prospective cohort study involving youth aged 9-21
Used OCT imaging to analyze neuroretinal layers
Moderate diabetic retinal disease was linked to a decrease in retinal nerve fiber layer thickness (-1.2 µm, P=.20)
GCL+IPL thickness was negatively associated with hemoglobin A1c (β = -0.39, P = .04)
Outer retinal layer thickness also showed a significant association with hemoglobin A1c (β = -0.81, P = .02)
