Area of Science:

  • Ophthalmology
  • Neuroscience
  • Psychiatry

Background:

  • Visual field defects can significantly impact daily life and require thorough investigation.
  • Differentiating organic from non-organic (functional) visual disturbances is crucial for accurate diagnosis and management.

Observation:

  • A 12-year-old female presented with acute left eye temporal hemianopia.
  • Ophthalmological examination and neuroimaging of the brain and opto-chiasmal region showed normal structural findings.
  • The visual field defect pattern was inconsistent with typical organic causes.

Findings:

  • Simultaneous binocular visual field testing revealed a consistent pattern despite the right eye's nasal hemifield being intact.
  • This finding supported the diagnosis of a non-organic visual field defect.
  • The patient's symptoms resolved following reassurance and placebo treatment.

Implications:

  • This case underscores the importance of considering non-organic visual disturbances in pediatric patients with seemingly clear visual field defects.
  • Functional visual loss can mimic organic conditions, necessitating careful diagnostic evaluation.
  • Psychological support and a placebo-controlled approach can be effective in managing non-organic visual symptoms.
