Damage in retinal periphery closely matches loss of blood flow in people with diabetes
Areas of non-perfusion were identified by UWF retinal angiography, which detects blood flow after patients are injected with a fluorescent dye. “With the UWF angiograms, we can more accurately measure the extent of non-perfusion in the peripheral and examine how this relates to the increased risk for retinopathy progression over time,” says Silva, who is lead author on the paper.
The areas of non-perfusion matched up very closely with the peripheral lesions detected when these patients’ eyes were scanned by normal UWF imaging, he emphasizes…….
