PURPOSE: To report the sudden onset of reversible Charles Bonnet syndrome precipitated byacute severe anemia. METHODS: The charts of three patients (Usher syndrome, bilateral macular degeneration, and bilateral retinal vein occlusion) with acute Charles Bonnet syndrome in the setting of severe anemia were reviewed. RESULTS: Anemia resulted from bladder surgery, recto-colitis, and severe urinary tract infection. Hemoglobin ranged from 78 to 86 g/L. Decreased visual acuity and formed visual hallucinations (giants, flowers, animals) were present in all three patients. Rapid reversal of Charles Bonnet syndrome and visual acuity improvement followed blood transfusion. CONCLUSIONS: Acute severe anemia can precipitate Charles Bonnet syndrome, which may be reversible by blood transfusion.
