Summary
Charles Bonnet syndrome causes visual hallucinations in individuals with vision loss. A case highlights that meningioma compressing optic nerves can be a rare cause, emphasizing thorough diagnosis.
Area of Science:
- Ophthalmology
- Neurology
- Neuro-ophthalmology
Background:
- Charles Bonnet syndrome (CBS) involves complex visual hallucinations in individuals with vision impairment.
- CBS affects all ages but is more prevalent in the elderly.
- The exact pathophysiology and a universal definition of CBS remain elusive.
Observation:
- A 72-year-old female, post-cataract surgery with severe vision loss, experienced visual hallucinations.
- Hallucinations occurred without other psychiatric symptoms.
- An extensive meningioma compressing the optic nerves was discovered during hospitalization.
Findings:
- The patient's visual hallucinations were attributed to optic nerve compression by a meningioma.
- This case suggests a broader differential diagnosis for CBS, including intracranial tumors.
- Accurate diagnostic evaluation is crucial for identifying underlying causes.
Implications:
- Intracranial pathologies, such as meningiomas, should be considered in the differential diagnosis of Charles Bonnet syndrome.
- Comprehensive neuro-ophthalmological evaluation is essential for patients presenting with unexplained visual hallucinations.
- Understanding diverse etiologies can improve patient management and outcomes for CBS.
