ABSTRACT
BACKGROUND: Toxoplasmosis is a zoonotic illness caused by Toxoplasma gondii. Ocular infection frequently manifests as acute necrotizing retinal chorioretinitis. In this paper, we describe a case of retinal chorioretinitis caused by Toxoplasma gondii infection, as well as the most recent diagnostic and treatment techniques. METHODS: Serum and vitreous fluid were collected and analyzed, and PCR for Toxoplasma gondii DNA, ELISA for Toxoplasma gondii IgG and Goldmann-Witmer coefficient, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), and fundus autofluorescence were done (FAF). RESULTS: Toxoplasma gondii DNA (-), serum and vitreous IgG from Toxoplasma gondii (+) cells, and the Goldmann-Witmer coefficient of Toxoplasma gondii were all considerably enhanced, indicating Toxoplasma gondii infection. Antiparasitic infection in combination with an anti-inflammatory glucocorticoid were given, laser treatment of the fundus was provided, and the patient's condition has been stable with no indication of recurrence to date following conclusion of therapy. CONCLUSIONS: Toxoplasma gondii can infect the whole retina, causing variable degrees of visual impairment; thus, rapid diagnosis and tailored therapy are necessary to enhance prognosis and reduce disease recurrence.
