Pulsatile 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),...
متن کاملDifferences in pulsatile ocular blood flow among three classifications of diabetic retinopathy.
PURPOSE Choroidal blood flow may be determined by pulsatile ocular blood flow (POBF) measurements. In the present study, the POBF of diabetic patients with increasingly severe retinopathy was compared with that in nondiabetic control subjects. METHODS The study was a masked cross-sectional analysis. Seventy-seven diabetic subjects, including 13 with mild or no retinopathy, 36 with moderate to...
متن کاملPulsatile Ocular Blood Flow in Healthy Koreans
PURPOSE To determine the normal reference range of pulsatile ocular blood flow (POBF) values in healthy Korean subjects and to find out the factors that may affect them. METHODS A total of 280 eyes of 280 normal subjects were included in this study. Best corrected visual acuity (BCVA), intraocular pressure (IOP), axial length, POBF, systemic blood pressure, and pulse rate were measured. The m...
متن کاملRetinal 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 کاملFactors affecting pulsatile ocular blood flow in normal subjects.
BACKGROUND The factors that influence pulsatile ocular blood flow (POBF) were evaluated in normal subjects. METHODS POBF was measured in 80 normal subjects using Langham OBF computerised tonometry. The effect of age, systolic and diastolic blood pressure, refractive error, intraocular pressure, and axial length on POBF was evaluated using multiple regression analysis. RESULTS The mean (SD) ...
