    Visual acuity in one eye improved for two patients when binocular vision was suspended or corrected with prisms. This suggests that oculomotor balance significantly impacts visual performance in certain gaze directions.

    Area of Science:

    • Ophthalmology
    • Neuroscience
    • Vision Science

    Background:

    • Binocular vision and oculomotor balance are crucial for visual acuity.
    • Fixation disparity and anisophoria can negatively impact visual performance.
    • The Turville Infinity Balance (TIB) test is used to assess binocular vision function.

    Purpose of the Study:

    • To investigate the effect of binocular vision suspension and prism correction on visual acuity in patients with amblyopia.
    • To explore the relationship between oculomotor balance, fixation disparity, and visual acuity.

    Main Methods:

    • Observed two patients experiencing visual acuity changes in one eye during binocular viewing.
    • Utilized the Turville Infinity Balance (TIB) test to assess visual acuity.
    • Administered prism correction based on anisophoria measurements to improve amblyopic eye vision.

    Main Results:

    • Visual acuity of the amblyopic eye improved when binocular vision was suspended (non-amblyopic eye covered).
    • Prism correction, tailored to anisophoria and fixation disparity, also enhanced the amblyopic eye's vision.
    • Demonstrated a correlation between variable monocular acuity, stereopsis, fixation disparity, and oculomotor balance.

    Conclusions:

    • Binocular vision and oculomotor status significantly influence monocular visual acuity.
    • Prism correction can be an effective strategy to improve visual function in cases of fixation disparity and anisophoria.
    • Further research is warranted to understand the complex interplay between oculomotor control and visual perception.
