OBJECTIVES To compare the retinal nerve fiber layer (RNFL) thickness and retinal sensitivity in the normal visual hemifield of glaucomatous eyes with localized visual field loss with those of normal eyes and eyes with suspected glaucoma, and to evaluate the relationship between RNFL atrophy and glaucoma severity. METHODS One randomly selected eye of each subject underwent standard automated p...

AIM This study was designed to test the ability of a portable computer driven, head mounted visual field testing system to perform automated perimetry on patients at their bedside and to compare these results with the "gold standard" for bedside examinations, confrontation visual fields. METHODS The Kasha visual field system is a portable automated perimeter which utilises a virtual reality h...

PURPOSE To examine the relationship between loss in peripheral visual sensitivity and neuropsychological functioning in seropositive patients with human immunodeficiency virus (HIV) without infectious retinopathy. METHODS Subjects carefully screened for retinal disease and well-matched across demographic and medical variables were grouped according to normal (perimetry-nl) versus abnormal (pe...

BACKGROUND The purpose of this study was to test the effect of ethyl alcohol on the koniocellular and magnocellular pathway of visual function and to investigate the relationship between such visual field changes and retrobulbar blood flow in healthy subjects. METHODS In 12 healthy subjects (mean age 32 ± 4 years), color Doppler imaging, short-wavelength automated perimetry, and frequency dou...

Purpose Peripheral vision is important for mobility, balance, and guidance of attention, but standard perimetry examines only <20% of the entire visual field. We report on the relation between central and peripheral visual field damage, and on retest variability, with a simple approach for automated kinetic perimetry (AKP) of the peripheral field. Methods Thirty patients with glaucoma (median...
