Background: Diabetic retinopathy (DR) is a common complication of type 2 diabetes and a major cause of vision loss in older adults. Platelet activation contributes to damage in small blood vessels. Platelet measurements such as mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR) may indicate this damage. This study aimed to compare platelet measurements in elderly diabetic patients with and without retinopathy and to assess their link to disease s
