Claim One:
1. A method for testing the visual field of a patient to determine an extent of at least one scotoma, comprising: measuring the visual perception of the patient by generating test images at a multiplicity of predetermined points on a visual field display viewed by the patient and recording the patient's responses to the test images to produce a set of raw data; and automatically analyzing said set of raw data to determine a closed curve generally separating points corresponding to unseen test images and points corresponding to seen test images, the analyzing of said raw data to determine said closed curve including: estimating a size and a shape of an area containing only points corresponding to unseen test images; based on the size and shape estimates, selecting a series of spaced points along a boundary of said area; and for each of said spaced points, more precisely determining the boundary of said area by automatically testing additional points located between points corresponding to unseen test images and points corresponding to seen test images.
