Intraocular parasites are uncommon occurrences in the USA. Diagnosis is dependent on the reliable history of ingested foods, geographic location, season, and direct visualization of the parasite with ophthalmoscopy. Various imaging modalities have also been applied in the study of intraocular parasites such as fluorescein angiography. Ultrasound biomicroscopy has been used to localize larvae when not seen on dilated fundus examination and scanning electron microscopy has aided morphological study for species determination.
While optical coherence tomography (OCT) has been utilized in visualizing tracks of nonspecific cutaneous larva migrans through the epidermis, its capabilities have yet to be explored with regard to complete visualization of an intraocular helminthic infection. We report a case in which spectral domain optical coherence tomography imaging of an intravitreal parasite was performed. The clinical presentation and pathological findings are most consistent with Gnathostoma spp.
