327-OR: Association of Retinol Binding Protein 3 with Retinal Neural Structure and Clinical Parameters in Diabetic Retinopathy
2020
The Joslin Medalist Study, which characterizes people with type 1 diabetes duration of 50 years or more, reported that the levels of Retinol Binding Protein 3 (RBP3) are increased in the retina and vitreous of Medalists who are protected from the development of severe diabetic retinopathy (DR). This protective capacity of RBP3 is potentially mediated by its ability to delay the uptake of glucose into the cells of the retinal vasculature and neural retina in hyperglycemia. This study correlated the relationship between DR severity and neural retinal layer thickness with vitreous and serum RBP3 levels in a broad population of people with diabetes. Optical coherence tomography (OCT) was performed to obtain neural retinal layer thicknesses and structure. Specific ELISA assays were developed to measure vitreous and serum RBP3 concentrations in individuals with type 1 and type 2 diabetes recruited from the Joslin Beetham Eye Institute, Medalist Study, and the FinnDiane study. Vitreous RBP3 concentration was associated with DR severity (p Disclosure W. Fickweiler: None. K. Park: None. E. Wolfson: None. H. Park: None. H. Yokomizo: None. I. Wu: None. D.
