Color space distortions in patients with type 2 diabetes mellitus [PDF]

open access: yes, 2006
Color vision impairment was examined in patients with type 2 diabetes mellitus (DM2) without retinopathy. We assessed the type and degree of distortions of individual color spaces. DM2 patients (n = 32), and age-matched controls (n = 20)were tested using
