PROGRESSIVE PERIPAPILLARY CHOROID THINNING AND RETINAL NEURODEGENERATION IN PATIENTS WITH DIABETES: A 3-Year Cohort Study.

Patients with Type 2 diabetes mellitus were at a higher risk of developing DR when accelerated pCT and pRNFLT thinning were present, indicating that heavier choroidal damage and retinal neurodegeneration precede clinical DR. The pCT and pRNFLT have the potential to serve as novel sensitive biomarkers of preclinical and early DR.
