Benign recurrent VI nerve palsy in childhood.
The case of a child with six documented episodes of benign recurrent unilateral VI nerve palsy between the ages of 2 1/2 months and 3 years is presented. Despite the recognized self-limiting course of this disorder, its possible evolution into a comitant esotropia makes close follow-up mandatory. The practical aspects of management including maintenance occlusion therapy are stressed as well as the need for prompt surgical intervention once the acquired stabismus has become stabilized. The etiology of benign VI nerve palsy of childhood may have the same immunological basis as other cases of para-infectious neuropathy. This isolated postinfective cranial mononeuropathy easily blends into the continuum of neurological involvement seen with the Landry-Guillian-Barre syndrome. With recovery from the initial episode, the abducens nerve may have become predisposed to recurrent inflammatory episodes and recurrent loss of function. Most often these recurrences are triggered by febrile illnesses of childhood.
