Panuveitis caused by Borrelia burgdorferi sensu lato infection.

A 13-year-old boy who presented with a red left eye, painful eye movement, blurred vision, photophobia and increased lacrimation, was diagnosed with 1-sided panuveitis with optic disk edema. Diagnostic work-up revealed borrelial antibodies in serum. Diagnosis of Lyme borreliosis was substantiated by demonstration of lymphocytic pleocytosis, intrathecal borrelial antibody synthesis, improvement after treatment with ceftriaxone and exclusion of other causes.
