Fasciola hepatica in the human eye.

During intraocular surgery of a 44-year-old woman from Guilan Province in north Iran, a small flat parasite was removed from the anterior chamber angle of the left eye. According to morphological characterisation of the parasite, it was identified as Fasciola hepatica. The route of entry of the parasite was not identified. Meanwhile, stool and serology examinations of the patient for diagnosis of Fasciola infection were negative. In endemic areas of F. hepatica infection, ocular involvement should be considered in cases of uveitis, despite no other systemic involvement.
