Abstract

We present a case of a patient with Anton's syndrome due to decompression illness (DCI) after recreational scuba diving. Visual anosognosia, or denial of loss of vision, which is associated with lack of awareness regarding visual loss in the setting of cortical blindness, is known as Anton's syndrome (also termed Anton-Babinski syndrome). Our patient presented with progressive neurological DCI treated with repeated recompression. The anosogosia resolved after 48 h. Subsequent echocardiography revealed a persistent (patent) foramen ovale.

“… 1 , 7 Other rare causes of Anton’s syndrome include brain tumors, 8 trauma, 9 neuroleptospirosis, 2 and decompression illness. 3 The patient described in the present report had Anton’s syndrome caused by Trousseau syndrome, which to the best of our knowledge has not been documented previously.…”

“…Anton’s syndrome is a rare neuropsychiatric syndrome that is characterized by cortical blindness and anosognosia with visual confabulation, without global cognitive impairment. 1 – 4 Anton’s syndrome (also called Anton–Babinski symptom) was named by Gabriel Anton and Joseph Babinski, and is characterized by confabulation as a result of the denial of vision loss. 6 That is, patients with Anton’s syndrome behave as if they can see despite obvious visual loss.…”

“…However, they strongly believe that they can see what they cannot, and they behave and talk as if they were sighted. Although some causes of cortical blindness may potentially result in Anton’s syndrome, 1 – 4 cerebrovascular disease—particularly bilateral occipital infarction—is the most common cause. 1 However, to the best of our knowledge, there have been no previous reports of Trousseau syndrome as the cause of Anton’s syndrome.…”
