Summary

Homonymous visual field defects are uncommon in multiple sclerosis (MS). This study details a rare case of quadrantanopia in a probable MS patient, linked to a small lesion, with complete recovery.

Area of Science:

  • Neuro-ophthalmology
  • Neuroscience
  • Demyelinating Diseases

Background:

  • Homonymous visual field defects in multiple sclerosis (MS) are typically associated with extensive white matter lesions affecting the posterior visual pathways.
  • The historical theory linking optic radiation lesions to quadrantic visual field deficits has faced recent scrutiny.

Observation:

  • A patient with probable MS presented with a congruous quadrantanopia, a specific type of homonymous visual field defect.
  • Imaging revealed a small white matter lesion located in the contralateral trigone area, a region not typically implicated in such defects.

Findings:

  • The small lesion in the trigone area was identified as the cause of the quadrantanopia.
  • The patient experienced a complete recovery of their visual field function.

Implications:

  • This case challenges the conventional understanding of lesion location and size required to cause homonymous visual field defects in MS.
  • It suggests that even small lesions in specific anatomical locations can lead to significant visual disturbances.
  • Further research may refine our understanding of MS pathophysiology and visual pathway involvement.
