1. A multiple site visual field testing system, comprising:
- a plurality of electronic image display devices, each said display device being constructed and positioned to display an electronic image encompassing the visual field of at least one eye of a patient;
a plurality of response sensing devices, each said response sensing device being adapted to sense a patient'"'"'s response to a visual stimulus and to generate a response signal;
a plurality of local signal processing systems, each said local processing system being connected to a respective said display device to generate said electronic image, each said local processing system being connected to a respective said response sensing device to receive said response signal;
a central processing system connectable to said plurality of local signal processing systems for controlling generation of said electronic images, and for receipt of said response signals from said plurality of local processing systems;
a neural network for automatic interpretation of said response signals; and
a central data repository for collection of data from said response signals, and for repetitive training of said neural network.

Abstract
A method and an apparatus for utilizing a central neural network and a central data bank to perform automatic interpretation of the visual function test parameters obtained in a plurality of visual field testing systems, for a plurality of patients, with control and response signals being transmitted via the Internet. The data produced by the testing systems are automatically analyzed and compared with patterns on which the neural network was previously trained, and clinical diagnoses for pathological conditions are thereby suggested to the respective clinician for each patient.
