Abstract
This case report describes a 7-year-old male patient with painless unilateral visual
impairment due to optic neuropathy confirmed by visual evoked potentials (VEP), which
was found to be attributed to neuroborreliosis. The diagnosis was confirmed by applying
both European (European Federation of Neurological Societies [EFNS]) and American
(Centers for Disease Control and Prevention [CDC]) criteria. Following intravenous
treatment with broad-spectrum antibiotics, his vision gradually improved. This case
report adds to the scarce evidence for an association between optic neuropathies and
neuroborreliosis. It illustrates that, although uncommon, the clinician should be
aware of the possibility of Lyme disease in patients with unilateral visual impairment
due to optic neuropathy. Recognition is especially important because visual acuity
can return to normal after adequate treatment. We reviewed the differences in criteria
by the European EFNS guidelines and the American CDC criteria for making the diagnosis.
