Ocular toxocariasis is caused by infection with the second-stage larvae of the roundworms Toxocara canis or Toxocara cati. The infection can have three primary presentations: 1) chronic endophthalmitis, 2) localized granuloma, and 3) peripheral granuloma. These photographs show a classic localized granuloma located over the optic nerve. Also shown are the appearance of the granuloma on B-scan echography and optical coherence tomography (OCT).
