Postural studies in pulsatile ocular blood flow: II. Chronic open angle glaucoma.
The pulsatile ocular blood flow (POBF) has been recorded in 15 patients with chronic open angle glaucoma. Measurements were performed during regular treatment with timolol 0.25% eyedrops, two weeks after withdrawal of this treatment, and then a further two weeks after its reinstitution. Readings were taken with subjects in both the erect and supine positions by means of a pneumotonometric probe...
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 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 کاملOcular Perfusion Pressure and Pulsatile Ocular Blood Flow in Normal and Systemic Hypertensive Patients
PURPOSE Glaucomatous neuropathy can be a consequence of insufficient blood supply, increase in intraocular pressure (IOP), or other risk factors that diminish the ocular blood flow. To determine the ocular perfusion pressure (OPP) in normal and systemic hypertensive patients. MATERIALS AND METHODS One hundred and twenty-one patients were enrolled in this prospective and comparative study and ...
متن کاملLocal anaesthetic techniques and pulsatile ocular blood flow.
AIM To compare pulsatile ocular blood flow (POBF) and intraocular pressure (IOP) between eyes of patients receiving either peribulbar (with and without balloon compression) or subconjunctival local anaesthesia (LA). METHODS 30 eyes of 30 patients undergoing cataract surgery by phacoemulsification were investigated in a study of parallel group design. Ten patients had peribulbar LA and 10 minu...
