%X 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.Ocular T. canis may present with retinal vasculitis in young patients in the setting of acute systemic infection.Toxocara canis (T. canis) is a ubiquitous parasite found worldwide. T. canis can only complete its lifecycle in dogs, and humans are accidental hosts [1,2]. Ocular T. canis is typically seen in children with an average age of diagnosis of 7.5 years [2,3]. The majority of patients present with blurred vision, pain, photophobia, and floaters. T. canis may demonstrate a localized disciform macular detachment, multifocal granulomas with interconnecting tracks, peripheral retinal detachment, papillitis, peripheral retinal mass, pars plana mass, vitritis, endophthalmitis, or cataract. The most common causes for vision loss in the setting of ocular T. canis are dense vitritis, cystoid macular edema, and tractional retinal detachment. Although animal models of T. canis infection uniformly demonstrate retinal vasculitis [4], this finding has not been previously reported in human eyes. We report a patient who presented with acute onset vision loss in the setting of constitutional symptoms and a positive T. canis ELISA. Interestingly, this patient had clinical and angiographic findings consistent with retinal vasculitis. To our knowledge, this is the first report of retinal vasculitis in ocular T. canis infection.A 16-year-old male presented with a 1 week history of left eye pain, floaters, and decreased visual acuity. His review of symptoms was significant for headache, sore throat, and cough occurring 1 week prior to his visual symptoms. He did not have any known history of animal exposure a
