Coinfection of Ocular Toxoplasmosis and Ocular Toxocariasis in the Same Patient.

To report a rare case of a toxoplasma chorioretinitis in one eye and peripheral ocular toxocariasis granuloma in the fellow eye of the same patient. Retrospective case report. A 44-year-old male presented with gradual loss of vision over the past weeks. The patient was diagnosed with ocular toxoplasma chorioretinitis recurrence in his right eye and an inactive peripheral granuloma of ocular toxocariasis was found in the left eye. The patient was a farmer who had been involved in animal husbandry throughout his life. The patient was treated with antibiotics for toxoplasma chorioretinitis and kept under follow-up for ocular toxocariasis. Coinfections of zoonoses are related to socioeconomic environment and individual characteristics of the host. Ocular toxoplasmosis and ocular toxocariasis may present with different scenarios. To our knowledge, this is the first case of a coinfection of ocular toxoplasmosis and ocular toxocariasis in the same patient. A thorough ophthalmological examination and detailed anamnesis are important for diagnosis.
