Retinal blood flow in diabetic retinopathy.
OBJECTIVES (a) To report on the basic parameters of retinal blood flow in a population of diabetic patients with and without retinopathy and non-diabetic controls; (b) to formulate a haemodynamic model for the pathogenesis of diabetic retinopathy from this and other studies. DESIGN Laser-Doppler velocimetry and computerised image analysis to determine retinal blood flow in a large cross secti...
متن کاملOcular 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 کاملOral Administration of Cilostazol Increases Ocular Blood Flow in Patients with Diabetic Retinopathy
PURPOSE To investigate the effect of cilostazol on ocular hemodynamics and to determine whether the administration of cilostazol increases the ocular blood flow in patients with diabetic retinopathy. METHODS This prospective observational study investigated the effect of orally administered cilostazol on diabetic retinopathy. Before and after administration for 1 week, pulsatile ocular blood ...
متن کاملEffects of photocoagulation on ocular blood flow in patients with severe non-proliferative diabetic retinopathy
PURPOSE To investigate ocular blood flow and correlations between ocular blood flow and variables in patients with severe non-proliferative diabetic retinopathy (S-NPDR) following panretinal photocoagulation (PRP). METHODS In this retrospective, cross-sectional study, the blood flow on the optic nerve head (ONH) and choroid was assessed with laser speckle flowgraphy (LSFG) using the mean blur...
متن کاملPulsatile ocular blood flow changes after panretinal photocoagulation treatment in patients with proliferative diabetic retinopathy.
BACKGROUND/AIM To prospectively assess the effects of panretinal photocoagulation (PRP) treatment on pulsatile ocular blood flow (POBF) in patients with proliferative diabetic retinopathy (PDRP). MATERIALS AND METHODS The study included 40 eyes with PDRP in 27 patients. The PRP treatments were completed in 3 sessions with 3-week intervals. The intraocular pressure (IOP), pulse amplitude (PA),...
