Ocular 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 کاملOcular Blood Flow and its Determination and Relevance in Glaucoma
Received for publication October2005 .................................. Although intraocular pressure (IOP) is closely linked to the pathogenesis of primary open angle glaucoma (POAG) and reduction of IOP slows down the glaucoma damage, 12% of subjunctives with controlled IOP continue to have progressive visual field loss and about 30% of glaucoma patients never experience high IOP. Clinical ex...
متن کاملCurrent Imaging Modalities for assessing Ocular Blood Flow in Glaucoma
Glaucoma may be caused by an interplay of elevated intraocular pressure (IOP), vascular, genetic, anatomical, brain, and immune factors. The direct assessment of ocular hemodynam-ics offers promise for glaucoma detection, differentiation, and possibly new treatment modalities. All the methods currently in use to measure ocular blood flow have inherent limitations and measure different aspects o...
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 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...
