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 کاملPulsatile ocular blood flow investigation in asymmetric normal tension glaucoma and normal subjects.
AIMS This study was designed to investigate pulsatile ocular blood flow (POBF) in normal tension glaucoma (NTG) patients and in normal controls. NTG patients with unilateral field loss were evaluated to compare POBF values between eyes with and without field loss. METHODS POBF measurements from more than 1500 subjects were collected during a period of 6 months from six optometric centres. Sub...
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 کاملWaveform analysis of ocular blood flow and the early detection of normal tension glaucoma.
PURPOSE To investigate waveform changes in blood flow (BF) in the optic nerve head (ONH) and to evaluate their usefulness in identifying normal tension glaucoma (NTG). METHODS Sixty-one eyes of 61 patients with NTG and 21 eyes of age-matched healthy control subjects were included in this study. The NTG eyes were divided into the following three groups based on the progression of their visual ...
متن کاملPeripapillary retinal blood flow in normal tension glaucoma
Aims—To determine if normal tension glaucoma (NTG) patients diVer from age matched controls in blood flow to the peripapillary retina, as measured with confocal scanning laser Doppler flowmetry (cSLDF; “Heidelberg retinal flowmetry”). Methods—12 NTG patients and 12 age matched controls were compared using (a) 10 × 10 pixel boxes (the instrument default sample size), taken from the nasal and tem...
