Humphrey visual field analysis, visual field defects, and ophthalmic findings in patients with macro pituitary adenoma.
OBJECTIVE To evaluate the Humphrey visual field parameters in patients with pituitary adenoma and classify the visual field defects in this patient group. METHODS Forty primary pituitary adenoma patients underwent neuro-ophthalmological examination and Humphrey Perimetry 30-2 visual field test at Baskent University, Departments of Ophthalmology, and Neurosurgery, between 2003 and 2005. Global...
متن کاملComparison of the monocular Humphrey visual field and the binocular Humphrey esterman visual field test for driver licensing in glaucoma subjects in Sweden
BACKGROUND The purpose of this study was to compare the monocular Humphrey Visual Field (HVF) with the binocular Humphrey Esterman Visual Field (HEVF) for determining whether subjects suffering from glaucoma fulfilled the new medical requirements for possession of a Swedish driver's license. METHODS HVF SITA Fast 24-2 full threshold (monocularly) and HEVF (binocularly) were performed consecut...
متن کاملComparison of contrast sensitivity, visual acuity, and Humphrey visual field testing in patients with glaucoma.
BACKGROUND Despite their normal or near-normal Snellen visual acuity, patients with glaucoma often complain of "poor" vision. OBJECTIVE To investigate the relationship between large-letter contrast sensitivity, high-contrast visual acuity, and visual field defects in patients with glaucoma who have 20/40 or better visual acuity. DESIGN Prospective, cross-sectional case series. PATIENTS AN...
متن کاملGlaucomatous visual fields. FASTPAC versus full threshold strategy of the Humphrey Field Analyzer.
PURPOSE This study examined how FASTPAC, a fast strategy for the Humphrey Field Analyzer (HFA), compares to the standard 4/2-dB full threshold strategy in patients with glaucoma. METHOD The author tested one eye each of 50 patients with glaucoma (23 with only relative defects, 27 with at least one absolute defect; age range, 25 to 79 years; median age, 61.5 years) with both strategies using p...
متن کاملWhy word length only matters in the left visual field.
During visual word recognition, string length affects performance when stimuli are presented to the left visual field (LVF), but not when they are presented to the right visual field (RVF). Using a lexical-decision experiment, we investigated an account of this phenomenon based on the SERIOL model of letter-position encoding. Bottom-up activation patterns were adjusted via positional manipulati...
