Design: Interventional case report. Method/Intervention: A live nematode was removed from the anterior vitreous cavity by pars plana vitrectomy. Results: The worm was successfully removed surgically, and the patient had an uneventful recovery. The nematode was identi- fied as an immature filaria, most likely a member of the genus Onchocerca. Conclusions: Only 3 previous reports exist of human infection of the eye caused by zoonotic Onchocerca, 2 involving the subconjunctiva and 1 the cornea. Although rare, zoonotic onchocercal infection of the eye must be considered a differential diagnostic entity even in temperate climates.展开更多
