PURPOSE We investigated the response of retinal vessel diameters and oxygen saturation to flicker light stimulation of neuronal activity in patients with diabetic retinopathy. METHODS We included 18 patients with nonproliferative diabetic retinopathy (mean age 62.2 ± 8.3 years, diabetes type 1 in 4 patients and type 2 in 14, hemoglobin A1c 7.7 ± 0.9%, duration of diabetes 24.1 ± 9.3 years) and 20 age-matched healthy controls (age 66.7 ± 10.3 years). Dual wavelength (548 and 610 nm) fundus… CONTINUE READING
