Abstract

Ocular Baylisascaris procyonis infection results from ingestion of infective eggs of B. procyonis, the raccoon ascarid. Herpes simplex virus type 2 (HSV-2) infection of the retina is the result of either primary infection or reactivated disease. Herein, we report a case of a 12-year-old female resident of the Bronx in New York City, who presented with pan-uveitis and vision loss. Initial evaluation for etiologic causes was nondiagnostic. Serology for anti-Baylisascaris procyonis antibodies in serum and vitreous fluid were both positive. Polymerase chain reaction (PCR) of vitreous fluid was positive for HSV-2. Treatment with vitrectomy, albendazole, and acyclovir resulted in mild improvement of visual acuity. The atypical presentation of B. procyonis in this case, as ocular larva migrans with a peripheral granuloma and retinal detachment, underscores the importance of maintaining a high degree of suspicion for this pathogen even in non-diffuse unilateral subacute neuroretinitis (DUSN) patients in urban areas. This case further illustrates that it is possible to have coexisting infections in cases of posterior uveitis.
