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 کاملTwenty-four hour (Nyctohemeral) rhythm of intraocular pressure and ocular perfusion pressure in normal-tension glaucoma.
PURPOSE To characterize the nyctohemeral rhythm of intraocular pressure (IOP) and ocular perfusion pressure (OPP) in patients with newly diagnosed, untreated normal tension glaucoma (NTG). METHODS Twenty-seven patients with suspected NTG were prospectively included and underwent 24-hour monitoring of IOP and blood pressure (BP), polysomnography, and nailfold capillaropathy. The nyctohemeral r...
متن کاملIntra-ocular pressure in primary congestive glaucoma.
THIS investigation was undertaken at the Institute of Ophthalmology, London, the patients being drawn from a series of 100 individuals. All of them suffered from glaucoma characterized by a clinical onset consisting of periodic halos, with episodes of blurred vision and ocular pain. They formed a group of primary glaucomas in the adult, defined in this paper as congestive. Other characteristics...
متن کاملNormal intra-ocular pressure.
INTRA-ocuLAR pressure varies from individual to individual, from right eye to left eye, and from time to time. Many manometric studies have been made on experimental animals but observations on human eyes have been few: Wessely (1915, 1916) found an average of 22 5 and 18X5 mm. Hg, and Seidel (1922) one of 20 and 25 5 mm. Hg. Tonometric studies of human eyes, however, have been many; the result...
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...
