LETTER RE: Anton syndrome as a result of MS exacerbation

Submitted August 16, 2017
I read with interest the Kim et al. case report detailing Anton syndrome (AS) in a patient with multiple sclerosis.1 Apart from visual anosognosia, confabulation is an important symptom of AS. It is important to remember that AS on occasion may be associated with Charles Bonnet syndrome characterized by visual loss and hallucinations. Apart from
imaging, cortical blindness with preserved pupillary reaction to light and accommodation, intact ocular movements, normal optic fundi, absent visual
evoked potential (VEP) and absent optokinetic nystagmus may all aid in securing a clinical diagnosis of AS.2,3
