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.

Mentions: Neurological examination revealed discrete paresis of the right hand, Babinski symptom, weakened knee reflexes, and no left ankle reflex. A CT scan of the head with administration of contrast medium and an MRI revealed a metastatic change in the left occipital irregular zone surrounded by an area of oedema of the white matter (Figures 2(a) and 2(b)). The patient was diagnosed with paracentral scotoma in the visual field related to the blind spot, located in the lower temporal quadrant, and lower sensitivity of the peripheral retina. The bottom of the cornea of the left eye was raised, resulting in blurred line vision. Visual evoked response testing showed prolonged latency and reduced amplitude of the left eye.
