Complex visual hallucinations in macular degeneration

Abstract

A previously healthy elderly patient with a recent onset of macular degeneration presented for evaluation of elaborate complex visual hallucinations. The patient's psychiatric evaluation and level of cognitive functioning were normal. A diagnosis of organic hallucinosis secondary to macular degeneration was made, and the hallucinations ceased with increased sensory stimulation in the hospital. Numerous diagnoses were considered and are discussed, including Charles Bonnet hallucinations and peduncular hallucinosis.
