HIGASHIDE, OCT and Angiography of Toxocara Granuloma
METHODS: A 26-year-old woman with a unilateral exudative macular
lesion, diagnosed as ocular toxocariasis, was examined by OCT and
fluorescein and indocyanine green angiography before and after
systemic steroid and anthelminthic therapy.
RESULTS: Initially, the macular granuloma appeared in OCT images as
a highly reflective mass protruding above the retinal pigment
epithelium (RPE) and showed dye leakage by angiography. After the
therapy, the lesion ceased being exudative and became an elevation
covered by the RPE in OCT images. There was reticular
hyperfluorescence surrounded by a hypofluorescent rim in the
angiograms.
CONCLUSIONS: Subretinal Toxocara granuloma may have a similar
clinical presentation as an idiopathic choroidal neovascularization
(CNV) and, therefore, should be included in the differential diagnosis
of the idiopathic CNV.
