Bottom Line: We present the cases of three patients who experienced complex visual hallucinations following various pathomechanisms.In two cases, diagnosis showed coexistence of occipital lobe damage with ocular damage, while in the third case it showed occipital lobe damage with retrobulbar optic neuritis.Theories of pathogenesis and the neuroanatomical basis of complex visual hallucinations are discussed and supported by literature review.

ABSTRACT
Charles Bonnet syndrome is an underrecognized disease that involves visual hallucinations in visually impaired patients. We present the cases of three patients who experienced complex visual hallucinations following various pathomechanisms. In two cases, diagnosis showed coexistence of occipital lobe damage with ocular damage, while in the third case it showed occipital lobe damage with retrobulbar optic neuritis. Theories of pathogenesis and the neuroanatomical basis of complex visual hallucinations are discussed and supported by literature review.

fig4: A CT image of the ischemic changes in the right occipital region.

Mentions: Neurological examination revealed blindness of the right eye, impaired visual acuity of the left eye, and mild left hemiparesis. Her mental status did not reveal any psychotic symptoms; she had preserved her sense of direction and was self-aware and capable of reality testing. The patient scored 29 on the Minimental State Examination. The ophthalmologic examination of the left eye revealed a major impairment of the visual field (impaired paracentral vision in the lower quadrants) and macular degenerative changes. Computed tomography examination showed an ischaemic vascular lesion localized to the right median occipital lobe (Figure 4). Perfusion CT revealed necrosis of the medial part of the occipital lobe and hypoperfusion of the right interior occipital cortex. Neither neuroimaging method showed any other pathologic changes.
