Retinal oxygen saturation is associated with HbA1c but not with short‐term diabetes control, internal environment, smoking and mild retinopathy ‐ ROXINEGLYD study
Abstract Purpose Purpose of this prospective uncontrolled single‐centre pilot study was to find an association of retinal oxygen saturation (SatO 2 ) with acid–base balance (ABB), carboxyhaemoglobin concentration, current plasma glucose concentration (PG), mean PG and PG variability over the last 72...
