The Effect of Glycemia on Choroidal Thickness in Different Stages of Diabetic Retinopathy

Abstract

CPG had the strongest correlation with CT in patients with NPDR (mild, moderate, and severe), but not in PDR and PRP PDR patients. Our study suggests that the glucose level at the time of the test should be aggregated to other systemic and ocular parameters, such as age and axial length, when studying the choroid using SD-OCT.
