• A display method has been developed for imaging the results of static perimetric examinations performed over contiguous areas of the central visual field. Points are examined using a rectangular coordinate pattern. A three-dimensional display surface is interpolated between the recorded points. A two-dimensional representation of the interpolated surface is then drawn, using superposition of foreground elements to produce an illusion of depth. Refinements of surface fit to the data points and truncation and rotation of the images allow immediate appreciation of visual field topography. The use of rectangular coordinate patterns increases the probability of detection of small defects and improves the resolution of structural detail.
