Charles Bonnet syndrome involves visual hallucinations in individuals with severe vision loss but normal cognition. This case highlights the syndrome in primary optic atrophy, emphasizing the need for further research.

Area of Science:

  • Ophthalmology
  • Neurology
  • Psychiatry

Background:

  • Charles Bonnet syndrome is characterized by visual hallucinations, sensory deprivation, and preserved cognitive function.
  • It often occurs in individuals experiencing significant vision impairment.

Observation:

  • An 80-year-old female with a history of poor vision since childhood presented with visual hallucinations.
  • She had total vision loss in the past year, with vision reduced to hand movements, and bilateral pseudoaphakia post-cataract surgery.

Findings:

  • The patient exhibited visual hallucinations secondary to bilateral primary optic atrophy.
  • Psychiatric and neurological examinations revealed normal cognitive functions and no other neurological pathology.
  • Routine and neuroradiologic investigations were unremarkable.

Implications:

  • This case expands the understanding of Charles Bonnet syndrome presentation, particularly in the context of primary optic atrophy.
  • Early diagnosis and appropriate management, such as olanzapine, can help alleviate symptoms.
  • Further research is warranted to fully elucidate the pathophysiology and optimal treatment strategies for this condition.
