Are retinal layer thickness changes on optical coherence tomography (OCT) imaging in youth with type 1 diabetes associated with glycemic outcomes and diabetic retinopathy?In this cohort study, thinning of the ganglion cell and inner plexiform layer (GCL+IPL) and outer retinal layers was associated with higher hemoglobin A (HbA). There was no difference in total retinal thickness, retinal nerve fiber layer thickness, GCL+IPL thickness, or outer retinal layer thickness by presence or absence of diabetic retinopathy or severity of retinopathy.Neuroretinal layer thinning was observed in youth with type 1 diabetes without clinically apparent retinopathy and was associated with higher HbA.
