Correlation between ocular perfusion pressure and ocular pulse amplitude in glaucoma, ocular hypertension, and normal eyes
BACKGROUND The purpose of this study was to investigate the correlation between ocular perfusion pressure and ocular pulse amplitude in glaucoma, ocular hypertension, and normal eyes. METHODS Ninety eyes from 90 patients were included. Thirty patients had been recently diagnosed with glaucoma and had no previous history of treatment for ocular hypotension, 30 had elevated intraocular pressure...
متن کاملEstimation of ocular volume from axial length.
BACKGROUND/AIMS To determine which biometric parameters provide optimum predictive power for ocular volume. METHODS Sixty-seven adult subjects were scanned with a Siemens 3-T MRI scanner. Mean spherical error (MSE) (D) was measured with a Shin-Nippon autorefractor and a Zeiss IOLMaster used to measure (mm) axial length (AL), anterior chamber depth (ACD) and corneal radius (CR). Total ocular v...
متن کاملOcular rigidity, ocular pulse amplitude, and pulsatile ocular blood flow: the effect of intraocular pressure.
PURPOSE The purpose of this study was to characterize the pressure-volume relation in the living human eye, measure the ocular pulse amplitude (OPA), and calculate the corresponding pulsatile ocular blood flow (POBF) in a range of clinically relevant IOP levels. METHODS Fifty patients with cataract (50 eyes) were enrolled in the study. After cannulation of the anterior chamber, a computer-con...
متن کامل[The ocular pulse].
The ocular pulse SIR,-The important editorial on the ocular pulse,' highlights the observations of the retinal arterial pulsations noted by early ophthalmologists. It was Thiel' who first attempted to quantify the recording of the transmitted pulsations which had become known as the tonometric sign as early as 1879. Priestley Smith' had clearly described the spontaneous vascular pulsations obse...
متن کاملDoes Fundus Fluorescein Angiography Procedure Affect Ocular Pulse Amplitude?
Purpose. This study examines the effects of fundus fluorescein angiography (FFA) procedure on ocular pulse amplitude (OPA) and intraocular pressure (IOP). Materials and Methods. Sixty eyes of 30 nonproliferative diabetic retinopathy patients (15 males, 15 females) were included in this cross-sectional case series. IOP and OPA were measured with the Pascal dynamic contour tonometer before and af...
