Longitudinal Metabolic Alterations of the Visual Cortex in Diabetic Retinopathy Rats Using High-Field Proton Magnetic Resonance Spectroscopy.

The visual impairment in diabetic retinopathy (DR) has been associated with the pathophysiological changes of the entire visual pathway. However, only a few studies have specifically examined dynamic metabolic changes in the visual cortex of DR. The purpose of the study was to longitudinally characterize dynamic metabolic alterations in the visual cortex of DR rats using 11.7 T proton magnetic resonance spectroscopy (
