    Summary
    This summary is machine-generated.

    A rare case of hypertropia from fourth-nerve palsy presented with voluntary nystagmus. Recognizing this benign finding is crucial to prevent unnecessary, risky diagnostic procedures for vertical nystagmus.

    Area of Science:

    • Ophthalmology
    • Neurology

    Background:

    • Fourth-nerve palsy can lead to complex ocular motor disturbances.
    • Hypertropia, an upward deviation of the eye, is a common sign of cranial nerve palsies.

    Observation:

    • A patient presented with primary position oscillations.
    • These oscillations mimicked voluntary nystagmus.
    • The underlying cause was identified as hypertropia secondary to fourth-nerve palsy.

    Findings:

    • The observed primary position oscillations were characteristic of voluntary nystagmus.
    • This presentation highlights a benign cause of vertical nystagmus.

    Implications:

    • Clinicians must consider voluntary nystagmus as a potential manifestation of fourth-nerve palsy.
    • Accurate diagnosis can prevent unnecessary and potentially hazardous investigations for vertical nystagmus.
