Compensatory contribution of retinal larger vessels to perfusion density in diabetics without retinopathy

Scientific Reports, 2022
Vessel and perfusion densities may decrease before diabetic retinopathy appears; it is unknown whether these changes affect the contribution of vessel density to perfusion density.
