HIGASHIDE, OCT and Angiography of Toxocara Granuloma
Text
A posterior pole granuloma

is a typical presentation of ocular
toxocariasis. However, the early subretinal lesion without uveitis
or tractional changes has not been well characterized. We studied
the features of a subretinal Toxocara granuloma with optical coherence
tomography (OCT) and fluorescein and indocyanine green angiography.
A 26-year-old woman presented with metamorphopsia and a
paracentral scotoma in her left eye of two weeks' duration. Her
best-corrected visual acuity was 20/100 in the left eye, and the
slit-lamp examination was normal. An ill-defined yellowish elevation
with a serous retinal detachment was present in the macula of the
left eye (Fig. 1). No abnormalities were seen in the right eye.
OCT
showed a highly reflective mass, surrounded by subretinal fluid,
protruding above the retinal pigment epithelium (RPE; Fig. 1).
Fluorescein angiography demonstrated central hyperfluorescence of
this macular lesion with late phase dye leakage (Fig. 1). ICG
angiography demonstrated an oval hypofluorescent lesion in the early
phase that became relatively hyperfluorescent from dye leakage in
