Automated suprathreshold static perimetry

C A Johnson, J L Keltner

    American Journal of Ophthalmology
    |May 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Automated kinetic perimetry using the Fieldmaster device accurately detects visual field defects. This technology also shows high reliability in monitoring the progression or regression of visual field loss over time.

    Area of Science:

    • Ophthalmology
    • Visual Neuroscience

    Background:

    • Kinetic perimetry is crucial for assessing visual field defects.
    • Evaluating automated perimetry devices is essential for clinical practice.

    Observation:

    • Automated (Fieldmaster) and manual kinetic perimetry were conducted on 1,019 eyes with diverse visual disorders.
    • The Fieldmaster system was evaluated for its efficacy in detecting visual field abnormalities and monitoring changes.

    Findings:

    • The Fieldmaster demonstrated a 96.1% detection rate for visual field defects with a 4.7% false alarm rate.
    • Follow-up testing with the Fieldmaster correctly identified progression or regression in over 94% of eyes with visual field changes.
    • The device showed 99% accuracy in identifying stable visual fields.
