Perimetry is a commonly used clinical test for visual function, limited by high variability. The sources of this variability need to be better understood. In this paper, we investigate whether noise intrinsic to neural firing could explain the variability in normal subjects. We present the most physiologically accurate model to date for stimulus detection in perimetry combining knowledge of the...
We report a 60-year-old woman with posterior cortical atrophy (PCA) who presented with left homonymous hemianopsia persisting for 5 years; the patient's condition was observed using static, but not kinetic, perimetry. This statokinetic dissociation of hemianopsia, which is often called Riddoch syndrome, might have been caused by a dysfunction of the right primary visual and visual association c...
A method of visual field examination is described which enables an unsupervised person to carry out self-assessment using only a paper test chart, a record sheet, and a pencil. It is entitled 'oculokinetic perimetry' because it is the subject's eye that moves and not the test target. By providing non-ophthalmic health care workers with a simple means of performing perimetry in the community, an...
