Toxoplasma retinitis following intravitreal injection of triamcinolone acetonide: A case report and review of literature.

The aim of this study was to report a case of atypical toxoplasma retinochoroiditis following intravitreal triamcinolone acetonide (IVTA) injection and to review the literature pertaining to toxoplasma retinochoroiditis following intravitreal injection of corticosteroid. Clinical data were collected from a 64-year-old male who developed toxoplasma retinitis 2 months after IVTA. A review of the literature was conducted to identify additional reports on similar cases. A 64-year-old male, known diabetic with nonproliferative diabetic retinopathy in both the eyes and optic atrophy in the left eye, presented with atypical retinitis inferior to the disc following IVTA. Real-time polymerase chain reaction and serology confirmed the toxoplasma etiology, and the patient was started on anti-toxoplasma therapy along with oral corticosteroid leading to regression of the lesion by 3 months. A high index of suspicion and proper microbiological diagnosis with appropriate antimicrobial therapy can aid in the management of toxoplasma retinochoroiditis following intravitreal injection of corticosteroid.
