“…No direct relation could be found between the pharmacological treatment, including anaesthesia medication, and the hallucinations. Yet, Tramadol might have exacerbated the phenomenon, as previously observed [17].…”

BackgroundWe report the first documented case of visual hallucinations with disembodiment and selfmotion illusion on eye closure. Clinical presentationA 71-year-old woman was operated on for a cyst of the left centrum semiovale, adjacent to the precuneus, the posterior cingulate cortex and the splenium of corpus callosum. Two days after, she complained of visual hallucinations occurring on eye closure. She reported reminiscences of landscapes, trees and animals. She had a sensation of floating and moving, flying over the landscapes or walking on lanes. She could stop the hallucinations by opening her eyes. The hallucinations lasted for six days. Pharmacological and neurological possible origins of the hallucinations were explored. ConclusionNo direct relation could be found between the pharmacological treatment and the hallucinations. Cerebral volumetric analysis showed a structural reorganization following cyst drainage, which might have conducted to transient hyper excitability of the surrounding structures. The release phenomenon induced by eye closure might have triggered the activation of a distributed network within associative visual, parietal and temporal cortices. The involvement of the splenium and the cingulum is discussed. Furthermore, MRI-and DTI-follow-up suggests that structural reorganization after surgery can be spread over long periods until disappearance of cyst-related deformations. Stabilization of cyst volume, near to zero, was observed after about 2 years.

Purpose Charles Bonnet syndrome (CBS) is a condition characterized by development of visual hallucinations in patients with no cognitive impairment and significant loss of vision mainly caused by age-related macular degeneration (AMD) or glaucoma. Methods This was a study of prevalence and characteristics of CBS diagnosed at the Neuroophthalmic Unit within the Ophthalmology Department of Hospital Clínico San Carlos (HCSC), Madrid, Spain. Results The CBS prevalence in patients from HCSC Madrid is 0.47%, rising to 15% in patients with low vision. Women over 80 years of age comprised 58.3% of the patients, who mainly had AMD (58.3%). Main characteristics of hallucinations included animals (50%), color (58.3%), moving (75%), 6- to 12-month evolution (50%), three times a day frequency (75%), and 3- to 5-minute duration (50%). Conclusions Charles Bonnet syndrome is a complex process that must be treated jointly by ophthalmologists, neurologists, and psychiatrists in order to ensure accurate diagnosis and adequate management. New studies are needed in order to improve awareness of clinical manifestation of this condition, the incidence of which is underestimated due to patients' fear of being branded mentally ill, as well as physicians' lack of knowledge about CBS.

“…The association of CBS with an external stimulus other that visual acuity loss is rare. Development of hallucinations in patients with CBS has been associated with several trigger factors including systemic diseases such as ischemic stroke, multiple sclerosis, and anemia as well as medical and surgical eye treatments 3,17–21. As noted earlier, only 1 case of a patient (who had age-related macular degeneration) experiencing visual hallucinations secondary to a hypertensive crisis has been previously reported 5.…”

Charles Bonnet syndrome (CBS) is a disorder of visual hallucinations in psychologically normal patients with ocular disease or damage to visual pathways. The etiology of CBS is not fully understood. It is associated with various triggers, with age-related macular degeneration the most common; other triggers are systemic diseases such as stroke, multiple sclerosis, and anemia as well as lighting issues, fatigue, and medical or surgical eye treatments. Visual disturbances such as decreased visual acuity, visual field deficits, or visual hallucinations are common in association with hypertensive encephalopathy. We describe a patient with episodic CBS triggered by recurrent hypertensive crises, which resolved with blood pressure management in the hospital setting.
