Background: Disorganization of the retinal inner layers (DRIL) on optical coherence tomography (OCT) is thought to represent retinal capillary nonperfusion (CNP) in eyes with diabetic retinopathy. This study was designed to evaluate the ability of DRIL to accurately predict CNP.

With ultra-widefield angiography, we have ascertained that posterior pole nonperfusion of more than 10 DA remains the key risk factor for new vessel development compared to areas of nonperfusion confined to the periphery.
