Abstract
PURPOSE: To report a case of a choroidal neovascularization (CNV) secondary to ocular toxocariasis treated with intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents. METHODS: A 66-year-old woman presented with decreased vision (20/40) and metamorphopsia in the right eye. Fundus examination revealed inferotemporal retinal whitish lesion and subretinal hemorrhage in the right eye. RESULTS: She was diagnosed with ocular toxocariasis based on the clinical features and positive serological anti-toxocara antibody test result. Ophthalmic examination revealed classic CNV formation adjacent to a retinal granuloma. She was treated with intravitreal ranibizumab and bevacizumab injections combined with oral albendazole. Her vision decreased to 20/100 following CNV recurrence. However, after additional bevacizumab treatment, the CNV became inactive and her vision recovered to 20/40. CONCLUSIONS: CNV can be combined with retinal granuloma due to ocular toxocariasis. Repeated intravitreal injections of anti-VEGF agents can be efficacious for regressing toxocariasis-associated CNV and improving vision.
