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 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 کاملOcular Blood Flow and Normal Tension Glaucoma
Normal tension glaucoma (NTG) is known as a multifactorial optic neuropathy characterized by progressive retinal ganglion cell death and glaucomatous visual field loss, even though the intraocular pressure (IOP) does not exceed the normal range. The pathophysiology of NTG remains largely undetermined. It is hypothesized that the abnormal ocular blood flow is involved in the pathogenesis of this...
متن کاملWeighing in Ocular Perfusion Pressure in Managing Glaucoma
The role of vascular risk factors in glaucoma is increasingly being supported by the literature, with the association between low ocular perfusion pressure (PP) and glaucoma being the most consistent result. However, we need to be cautious when interpreting these results and consider all possible confounders in the observed associations. While we assess PP through its principal components, the ...
متن کاملOcular blood flow and systemic blood pressure in patients with primary open-angle glaucoma and ocular hypertension.
PURPOSE There is evidence that altered optic nerve head (ONH) blood flow may play a role in the development and progression of glaucoma. In the present study, the baseline characteristics were examined in a study population participating in a clinical trial in which the ocular hemodynamic effects of timolol and dorzolamide were compared. METHODS One hundred forty patients with primary open-an...
