Diplopia: An Overlooked Feature in Patients With Neurosyphilis. Report of 2 Cases and Literature Review.

Both neurosyphilis and diplopia are widely known medical terms. Nevertheless, low clinical awareness by the physician and the often-overlooked presentation of diplopia, make the combination of neurosyphilis and diplopia rarely observed. In this article, we report 2 neurosyphilitic patients presenting with diplopia and review 8 additional case reports of neurosyphilis with diplopia, with a total of 10 cases to be analyzed.
