    This study introduces a fast, low-cost microcomputer system for central visual field testing. The technology provides quantitative analysis maps for improved patient care.

    Area of Science:

    • Ophthalmology
    • Medical Technology
    • Neuroscience

    Background:

    • Accurate assessment of the central visual field is crucial for diagnosing and monitoring various ocular and neurological conditions.
    • Existing visual field testing methods can be time-consuming, expensive, or require specialized equipment.

    Purpose of the Study:

    • To develop and evaluate a low-cost, efficient microcomputer-based system for central visual field examination.
    • To assess the feasibility of using standard peripherals for visual field testing.

    Main Methods:

    • Utilized a low-cost microcomputer with standard peripherals to test the central visual field up to 20 degrees.
    • Developed a rapid testing protocol, completing in five to eight minutes.
    • Implemented display of visual field maps on a television screen or via printout for quantitative analysis.
