Reproducibility of topographic measures of the glaucomatous optic nerve head.
AIMS/BACKGROUND Laser scanning tomography provides an assessment of three dimensional optic disc topography. For the clinical purpose of follow up of glaucoma patients, the repeatability of the various measured variables is essential. In the present study, the reproducibility of morphometric variables calculated by the topographic scanning system, TopSS (Laser Diagnostic Technology, San Diego, ...
متن کاملP 302 Reproducibility of optic nerve head topographic measurements with the glaucomascope (3.10)
Purpose: ‘This study describes hemodynamic characteristics of the retrobulbar circulation in ten eyes with acute anterior ischemic optic neuropathy (AION), in order to better understand Ihe natural history of this disease. Methods: Color Doppler imaging was used to measure the peak systolic blood flow velocities and vascular resistance (resistive index) within the central retinal, ophtalmic, an...
متن کاملReproducibility of the measurements of the optic nerve head topographic variables with a confocal scanning laser ophthalmoscope.
PURPOSE To determine the optic nerve head topographic parameters with the least variability in repeat measurements. METHODS We randomly selected and evaluated 1 eye each of 20 healthy subjects, a total of 20 eyes. We used the confocal scanning laser ophthalmoscope (CSLO) for optic nerve head analysis. The disc area and a total of 13 parameters were determined by Top SS. Each subject was exami...
متن کاملThe correlation between optic nerve head topographic measurements, peripapillary nerve fibre layer thickness, and visual field indices in glaucoma.
AIMS To establish whether the structural parameters provided by the Heidelberg retina tomograph (HRT) and the laser diagnostics glaucoma scanning system (GDx) can be used to reflect functional damage in the visual field. METHODS 62 patients with primary open angle glaucoma underwent examination with the HRT, GDx, and Humphrey field analyser. The relations between the topographic parameters, r...
متن کاملThe optic nerve head in myocilin glaucoma.
PURPOSE Approximately 1 in 30 unselected patients with open-angle glaucoma (OAG) have a mutation in the myocilin gene. The purpose of this study was to describe the morphologic features of the optic nerve head (ONH) in myocilin glaucoma. METHODS A case-control design was adopted. Sixty-six patients heterozygous for a range of myocilin mutation (cases) were matched in disease severity to 105 p...
