Analysis of correlations between biomarkers assessed with swept-source OCT and OCT angiography in naïve patients with diabetic macular edema treated with aflibercept: a prospective study

Treatment-naïve DME eyes treated with aflibercept showed significant structural, vascular, and functional improvements, with several baseline biomarkers acting as potential predictive indicators of posttreatment outcomes. The very high correlation of CCT and AADP and the high correlation of VD suggest that SS-OCT and SS-OCTA can provide clinically useful information for identifying how patients will respond to treatment. These correlations support the role of SS-OCT and SS-OCTA not only as diagnostic tools but also as potential predictive indicators of therapeutic response, facilitating more personalized DME management in clinical practice. Notably, this is the first prospective study to evaluate correlations between SS-OCT and SS-OCTA biomarkers in naïve DME eyes treated with aflibercept.
