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 کاملOcular rigidity, outflow facility, ocular pulse amplitude, and pulsatile ocular blood flow in open-angle glaucoma: a manometric study.
PURPOSE To compare ocular rigidity (OR) and outflow facility (C) coefficients in medically treated open-angle glaucoma (OAG) patients and controls, and to investigate differences in ocular pulse amplitude (OPA) and pulsatile ocular blood flow (POBF) between the two groups. METHODS Twenty-one OAG patients and 21 controls undergoing cataract surgery were enrolled. Patients with early or moderat...
متن کاملPulsatile ocular blood flow in patients with low tension glaucoma.
Measurements of the intraocular pressure (IOP) pulse and pulsatile ocular blood flow (POBF) have been made in 22 patients with bilateral low tension glaucoma (LTG) and 29 healthy subjects matched as closely as possible for age, refractive error, IOP, systemic pulse pressure, and heart rate. Recordings were made in both the standing and supine positions. The amplitude of the intraocular pressure...
متن کاملChronic open-angle glaucoma and ocular hypertension. An epidemiological study.
An epidermiological study of patients with chronic simple glaucoma or ocular hypertension suggests that the diagnosis of glaucoma is associated with a positive family history, acute blood loss, and diabetes mellitus. There was no association with other vascular disease or with smoking. Ocular hypertension was related to smoking habits but not to family history. The relationship of these variabl...
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...
