CHARACTERIZATION OF VISUAL FIELD DEFECTS

摘要

A method and apparatus for electronically performing a visual field test for a patient. A visual field test pattern (102) is displayed to the patient on an electronic display device (101) and the patient's responses to the visual field test pattern (102) are recorded. A visual field representation is generated from the patient's responses. The visual field representation is then used as an input into a variety of automated diagnostic processes. In one process, the visual field representation is used to generate a statistical description of the rapidity of change of a patient's visual field at the boundary of a visual field defect. In another process, the area of a visual field defect is calculated using the visual field representation. In another process, the visual field representation is used to generate a statistical description of the volume of a patient's visual field defect.
