Summary
Charles Bonnet syndrome (CBS) can cause visual hallucinations after eye procedures. This case highlights its rapid onset following eye patching post-vitrectomy, emphasizing the need for surgeon awareness and patient reassurance.
Area of Science:
- Ophthalmology
- Neurology
- Visual Science
Background:
- Charles Bonnet syndrome (CBS) involves visual hallucinations in individuals with maintained cognitive function.
- It is often associated with vision loss, but the specific triggers and onset speed can vary.
- Pars Plana Vitrectomy is a common surgical procedure to treat various retinal conditions.
Observation:
- A 48-year-old woman developed vivid, formed visual hallucinations shortly after left eye patching post-Pars Plana Vitrectomy.
- Hallucinations began less than 30 minutes after eye patching.
- These visual disturbances persisted for two days even after the eye patch was removed.
Findings:
- This case demonstrates an unusually acute onset of Charles Bonnet syndrome.
- The syndrome was directly linked to monocular visual deprivation via eye patching.
- The hallucinations were characterized as formed and vivid, typical of CBS.
Implications:
- Ophthalmic surgeons should be aware of the potential for rapid-onset CBS following procedures involving eye patching.
- Early recognition and appropriate patient counseling are crucial for managing CBS symptoms.
- Understanding acute CBS triggers can improve patient care and reduce anxiety after ophthalmic surgery.
