Ocular blood flow velocities in patients with proliferative diabetic retinopathy and healthy volunteers: a prospective study.
BACKGROUND Diabetes affects the vascular ocular circulation. Colour Doppler imaging allows for simultaneous two dimensional anatomical imaging and Doppler evaluation of blood flow velocity; with this technique ocular blood flow velocity can be evaluated in normal and diabetic patients. METHODS A prospective study compared blood flow velocity in ocular vessels (ophthalmic artery, posterior cil...
متن کاملColor Doppler imaging: a new technique to assess orbital blood flow in patients with diabetic retinopathy.
PURPOSE Color Doppler imaging is a new noninvasive technique that enables measuring blood flow velocity in small orbital vessels, arteries as well as veins. Because hemodynamic changes are seen in patients with diabetic retinopathy by other techniques, the authors compared 61 eyes with proliferative, 59 eyes with nonproliferative, and 26 eyes with preproliferative diabetic fundus changes with a...

Background: Microangiopathy and macroangiopathy frequently coexist in type 2 diabetes mellitus (T2DM). Both types of the vascular complications share traditional risk factors but it is not clear whether the presence of microangiopathy, such as diabetic retinopathy, constitutes a predictor of atherosclerosis in carotid arteries in patients with the disease. In this study we looked for the associ...
متن کاملAltered retrobulbar vascular reactivity in early diabetic retinopathy.
AIM/BACKGROUND In diabetic eye disease the factors leading to compromised circulation and the resulting loss of visual function are poorly understood. Although retinal circulation has been widely investigated, it accounts for only a fraction of total eye blood flow. Blood flow was investigated in the larger vessels feeding the eye in patients with early diabetic retinopathy. METHODS Eleven pa...
متن کاملColor Doppler imaging of the retrobulbar vessels in diabetic retinopathy
Diabetes is a metabolic disease characterized by elevated blood glucose level due to impaired insulin secretion and activity. Chronic hyperglycemia leads to functional disorders of numerous organs and to their damage. Vascular lesions belong to the most common late complications of diabetes. Microangiopathic lesions can be found in the eyeball, kidneys and nervous system. Macroangiopathy is ass...
