Background
We treated a rare case of Charles Bonnet syndrome (CBS) manifested during temporary blindness in both eyes caused by optic
neuritis associated with a first attack of multiple sclerosis (MS).
Case
A 66-year-old Japanese woman became completely blind for 3 months due to optic neuritis after a first attack of MS. During
the blind period, she experienced vivid visual hallucinations for about 2 weeks.
Observations
The patient had no psychiatric disorders or cognitive impairments; therefore, the visual hallucinations during the period
of blindness were indicative of CBS. Unexpectedly, the hallucinations disappeared without treatment following her recovery
of vision.
Conclusions
Although rare, visual impairment during a first attack of MS can be associated with visual hallucinations indicative of CBS.
The hallucinations can disappear spontaneously with the recovery of vision without treatment. Jpn J Ophthalmol 2005;49:533–534 © Japanese Ophthalmological Society 2005
