title: [Two cases of Parkinson's disease in which visual hallucinations disappeared after cataract surgery].
abstract: We report two cases of Parkinson's disease in which visual hallucinations disappeared after cataract surgery. Patient 1 was a 72-year-old woman with Parkinson's disease, visual hallucinations and musical hallucinations. Patient 2 was a 77-year-old woman with Parkinson's disease and visual hallucinations. Both patients had severe bilateral cataracts. Though it was difficult to control their visual hallucinations with medication only, cataract surgery made them disappeared quickly. The visual hallucinations of Parkinson's disease are similar to those of Charles Bonnet syndrome. For example, both hallucinations often happen in dim light, at night and when patients are awake with eyes open. Though there have been many reports describing visual hallucinations in Parkinson's disease, there have been few reports discussing the relation between these hallucinations and impaired visual acuity. Similar to the hallucinations of Charles Bonnet syndrome, impaired visual acuity should be related to the visual hallucinations of Parkinson's disease. When Parkinson's disease, visual hallucinations and severe cataract coexist, visual hallucinations may disappear after cataract surgery.
