Normal and abnormal space perception.

H E Bedell, M C Flom

    American Journal of Optometry and Physiological Optics
    |June 1, 1983

    Summary
    This summary is machine-generated.

    Strabismic amblyopic eyes exhibit significant spatial imprecision, not just distortions. This lack of spatial accuracy contributes to reduced visual acuity and abnormal eye movements in individuals with strabismus.

    Area of Science:

    • Vision Science
    • Neuroscience
    • Ophthalmology

    Background:

    • Normal spatial judgments are accurate.
    • Strabismus can impair spatial sense development.
    • Previous work showed spatial distortions in strabismic amblyopic eyes.

    Purpose of the Study:

    • Quantify spatial precision in strabismic amblyopic eyes.
    • Incorporate spatial imprecision into the hypothesis for abnormal visual behavior.

    Main Methods:

    • Quantification of spatial precision measures.
    • Comparison of spatial sense in strabismic amblyopic eyes versus non-squinting anisometropes.

    Main Results:

    • Strabismic amblyopic eyes demonstrate extensive spatial imprecision.

  • Spatial imprecision is a characteristic of the strabismic amblyopic eye's space sense.

    • Conclusions:

    • Spatial imprecision is a key factor in the abnormal sensory and motor behaviors of strabismic amblyopic eyes.
    • The updated hypothesis includes both spatial distortions and imprecision.
