    Area of Science:

    • Neurology
    • Ophthalmology
    • Neuroscience

    Context:

    • Peripheral and central nervous system lesions can affect visual-motor functions.
    • Accurate differential diagnosis is crucial for effective patient management.

    Purpose:

    • To evaluate the diagnostic utility of the vertical "X" sign test.
    • To differentiate between peripheral and central neurological lesions using this test.

    Summary:

    • The vertical "X" sign test was performed on 180 patients with peripheral or central lesions and 150 healthy controls.
    • Peripheral lesions were associated with directed deviations (75.3%), whereas central lesions showed undirected deviations (65.6%).

    Impact:

    • The vertical "X" sign test provides a valuable tool for differential diagnosis of neurological lesions.
    • Findings can help clinicians distinguish between peripheral and central visual-motor impairments.
