title: Sampling systems for visual field assessment and computerised perimetry.
abstract: Three successive stages in the representations of the visual image are studied by computations from the best available data. The results are embodied in projections, drawn automatically. These projections are related to the assessment of visual disability and the dimensions of lesions in the retina and visual pathway. Fields can be assessed visually with the aid of graticules or directly during computerised perimetry.
