Optical coherence tomographic and angiographic findings of a case with subretinal toxocara granuloma

Abstract Purpose To study a case with a subretinal Toxocara granuloma. Design Interventional case report. Methods A patient with a exudative macular lesion, diagnosed as ocular toxocariasis, was examined with optical coherence tomography (OCT) and angiography before and after systemic corticosteroid and anthelminthic therapy. Results In OCT images, the macular granuloma initially appeared as a highly reflective mass protruding above the retinal pigment epithelium and showed dye leakage by angiography. Posttherapy, the lesion was no longer exudative, was less elevated, and was covered by the retinal pigment epithelium. There was reticular hyperfluorescence surrounded by a hypofluorescent rim in the angiograms. Conclusions Subretinal Toxocara granuloma may have a presentation similar to idiopathic choroidal neovascularization (CNV) and should be included in the differential diagnosis of the idiopathic CNV.
