The relationship of visual threshold and reaction time to visual field eccentricity with conventional automated perimetry
To investigate the relationship between reaction time (RT), stimulus intensity and visual field eccentricity. We generated frequency of seeing (FOS) curves and measured RTs by testing 10 perimetrically experienced normal subjects with a Humphrey perimeter controlled by a custom program. Subjects were tested from 10 degrees to 50 degrees eccentricity along the nasal horizontal meridian in 10 deg...
متن کاملAutomated static perimetry: the influence of myopic anisometropia on evaluation of visual field.
The aim of study was to establish which level of myopic refractive error influences visual field defects in automated static perimetry, if these defects are typical, and if optimal correction normalized the visual field. The study included 100 patients (200 eyes) divided into three groups according to the severity of the myopic refractive error: group A (till -3.25 Dsph), group B (-3.50 Dsph to...
متن کاملIdiopathic intracranial hypertension and visual function.
BACKGROUND Idiopathic intracranial hypertension is a relatively common condition (incidence up to 19/100 000/year in the high-risk group of obese women in reproductive age range) causing headaches with papilloedema. Detailed investigations are required to exclude other causes of raised intracranial pressure. The condition may be self-limiting or enter a chronic phase with significant morbidity ...
متن کاملPerceptual relevance of abnormal visual field representations: static visual field perimetry in human albinism.
BACKGROUND In human albinism the plasticity of the visual system is challenged, as part of the temporal retina projects abnormally to the contralateral hemisphere. AIM To investigate whether the sensitivity of the abnormally projecting temporal retina is preserved. METHODS Light spot detection sensitivities were assessed in the central 20 degrees of the visual field in 15 patients with albi...
متن کاملQuantification 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...
