Self-limiting fourth and sixth cranial nerve palsy after Lyme disease.

Lyme disease, or borreliosis, is caused by a bacteria (Borrelia burgdorferi sensu lato) and is transmitted to humans by the bite of ticks of the Ixodes genus. The authors describe a 16-year-old girl who presented with extraocular muscle palsies and had serology positive for Lyme disease. The muscle palsies resolved after antibiotic treatment with no residual limitation of ocular movements.
