Bitemporal hemianopia, often caused by pituitary adenomas, impairs vision, making driving unsafe. Despite seemingly adequate visual fields, patients experience dangerous visual distortions, rendering them ineligible for driving.

Area of Science:

  • Ophthalmology
  • Neurology
  • Visual Neuroscience

Background:

  • Pituitary adenomas and chiasmal diseases commonly cause bitemporal hemianopia.
  • German traffic regulations (FeVAndV) require a minimum 120-degree visual field for driving eligibility.
  • Existing reports often inadequately address road traffic suitability for patients with visual field defects.

Observation:

  • A patient with bitemporal hemianopia presented with non-corresponding temporal retinal fields and diplopia due to exotropia.
  • Eye muscle surgery to correct diplopia resulted in esotropia and a vertical scotoma.
  • This case highlights the complex visual disturbances in bitemporal hemianopia.

Findings:

  • Undisturbed nasal visual half-fields in bitemporal hemianopia do not form a unified, near-normal visual field.

  • Visual field defects can lead to diplopia or dangerous central vertical scotomas.
  • Hemifields slide without retinal correspondence, disrupting visual perception.

    • Implications:

    • Bitemporal hemianopia significantly impairs a patient's ability to perceive daily life and traffic accurately.
    • The peripheral visual field extent is not the primary determinant of driving capability.
    • Individuals with bitemporal hemianopia are generally unfit to drive cars or motorcycles.
