We report a 26 year-old male patient who had floaters and hyperemia in his left eye following uveitis due to gnathostoma that had migrated into the vitreous cavity. Severe iridocyclitis and mild opacity of the vitreous body were observed, together with whitish-yellow subretinal tracks accompanied by dot and blot hemorrhages in the fundus. Slit lamp microscopic examination revealed a worm which writhed in the vitreous cavity. We performed vitrectomy to remove the worm from the anterior vitreous uneventfully, followed by prompt subsidence of the inflammatory signs. The worm was identified as a third instar larva of Gnathostoma doloresi. Eosinophilia and creeping eruption did not appear throughout the follow-up period. The patient was accustomed to eat live roaches and whitebait, as well as sliced raw beef liver.
