Acute Reversible Charles Bonnet Syndrome Following Eye Patch Placement

摘要

Charles Bonnet syndrome (CBS) is characterised by recurrent vivid visual hallucinations in the presence of normal cognition. We present a case of CBS secondary to eye patching following Pars Plana Vitrectomy with an unusually acute onset in a 48-year-old woman. She presented with formed visual hallucinations that started less than 30 min after patching of her left eye. The patch was removed after 2 d, and these hallucinations persisted 2d following eye patch removal. It is important that the ophthalmic surgeon be aware of the potential for development of CBS and offer appropriate referral and reassurance should it occur.
