[Isolation of Dirofilaria repens in vitreoretinal findings].

The authors present the case of a 18-year-old patient who reported deteriorated vision and mobile dark shadows on the left eye. Examination revealed in the vitreous body an extremely mobile filiform, worm-like formation, white in colour, of the size of an arteriole, about 9 mm long. In the course of hospitalization the formation was isolated by surgery of the pars plana vitrectomy and subjected to detailed helminthological examination. The worm was identified as Dirofilaria repens (Reillet et Henry 1911) and described in detail. The presented finding is the first finding of this parasite in this country and at the same time the first finding of this parasite in Czechoslovakia.
