Intraocular live cysticercus larva.

Ocular cysticercosis is one of the most common parasitic infections of the eye in humans. Although the adult pork tapeworm, Taenia solium, resides in the lumen of the intestine, the only structural element of an adult worm is usually found within a tissue cyst in the eye, its adenexa, or other places in the body with a single invaginated scolex. An unusual case is described in which a 13- to 14-mm live cysticercus larva was found, removed from the eye, and confirmed by histopathologic examination.
