Quantification of glaucomatous visual field defects with automated perimetry.
A method to quantify different glaucomatous visual field defects is presented. Three visual field indices are calculated: the short-term fluctuation, the mean defect, and the corrected loss variation. The method was applied to visual fields tested with program JO on the Octopus automated perimeter. The indices of 130 glaucoma suspects and 50 glaucoma patients were compared with 100 normal contr...
متن کاملMapping of glaucomatous visual field defects by multifocal VEPs.
PURPOSE To objectively measure a visual field and to sensitively detect glaucomatous visual field defects by measuring the contrast sensitivity function (CSF), using multifocal visual evoked cortical potentials (MVEPs). METHODS MVEPs of normal subjects (n = 28) and of patients with glaucoma (n = 12) or ocular hypertension (OH, n = 1) were recorded. A multi-input procedure was used to obtain 3...
متن کاملIdentification of glaucomatous visual field defects from examination of monocular photographs of the optic disc.
A study was carried out of monocular disc photographs from 33 eyes for which the visual fields on both static profile and kinetic perimetry has been performed. Physical signs looked for at the optic disc included thinning of the neuroretinal rim, angulation of retinal vessels, extension of laminar dots, undercutting of the neuroretinal rim, and absence and pallor of the neuroretinal rim. These ...
متن کاملDetection of central visual field defects in early glaucomatous eyes: Comparison of Humphrey and Octopus perimetry
PURPOSE To compare the detection rate of central visual field defect (CVFD) between the 30-degree Octopus G1 program (Dynamic strategy) and the HFA 10-2 SITA-Standard test in early glaucoma eyes not showing any CVFD on the HFA 24-2 SITA-Standard test. METHODS One eye of 41 early glaucoma patients without CVFD in the central 10° on HFA 24-2 test was tested with both the HFA 10-2 test and the O...
متن کاملPrevalence and nature of early glaucomatous defects in the central 10° of the visual field.
IMPORTANCE The macula is essential for visual functioning and is known to be affected even in early glaucoma. However, little is currently understood about the prevalence and nature of central vision loss in early glaucoma. OBJECTIVE To determine the prevalence and characteristics of visual field (VF) defects in the central 10° in glaucoma suspects and patients with mild glaucoma using a pros...
