A new apparatus for visual field testing with binocular fixation.

E Hasegawa

    Acta Medica Okayama
    |July 1, 1978
    PubMed
    Summary

    A novel instrument enables accurate and rapid detection of central visual field defects using binocular fixation. This visual field examination tool also quantitatively assesses suppression scotoma in conditions like amblyopia.

    Area of Science:

    • Ophthalmology
    • Visual Neuroscience

    Background:

    • Accurate assessment of the central visual field is crucial for diagnosing conditions like maculopathy and optic neuropathy.
    • Existing methods may have limitations in precisely quantifying certain visual field deficits, particularly those related to binocular vision anomalies.

    Observation:

    • A new instrument utilizing polarizing plates for binocular vision dissociation during visual field testing was developed.
    • The apparatus allows for steady binocular fixation on a central point while a testing chart is presented monocularly.

    Findings:

    • The instrument accurately and quickly detects central visual field changes caused by maculopathy or optic neuropathy.
    • It quantitatively measures suppression scotoma, a key indicator in amblyopia and squint, with improved precision.

    Implications:

    • This device offers a more comprehensive approach to visual field examination, integrating central field assessment with the detection of binocular vision disorders.
    • The quantitative measurement of suppression scotoma could lead to improved diagnostic capabilities and treatment monitoring for amblyopia and strabismus.
