Retinal vasculitis in Toxocara canis neuroretinitis

BACKGROUND: The purpose of this case report is to describe clinical and angiographic findings of retinal vasculitis in acute Toxocara canis neuroretinitis associated with systemic infection. FINDINGS: A 16-year-old male presented with a 1 week history of left eye pain, floaters, and decreased visual acuity. Ocular examination was consistent with neuroretinitis and retinal vasculitis. Fluorescein angiography demonstrated leakage of fluorescein from the optic nerve and the retinal veins. Clinical and laboratory evaluation were consistent with systemic Toxocara canis infection. CONCLUSIONS: Ocular T. canis may present with retinal vasculitis in young patients in the setting of acute systemic infection.
