Abstract

Ocular cysticercosis is caused by Cysticercus cellulosae. It is the larval form of pork tapeworm, Taenia solium. Rarely, it is caused by the larvae of beef tapeworm, T. saginata. Taeniasis is commonly seen in Southern American continent, Eastern part of European continent, China and Southeast Asia. The life-cycle of Taenia solium involves humans as the definitive host and pig as the intermediate host. Similarly, life-cycle of Taenia saginata involves humans as the definitive host and cow as the intermediate host. Infections with T. solium may be asymptomatic. Mostly seen in young individuals but can happen at all ages. There can be fever, fatigue and eosinophilia. Usually the diagnosis of ocular cysticercosis is clinical. B-scan ultrasonography is useful diagnostic test as it can show the location of the cyst, the number of cysts and other coexisting complications like retinal detachment especially when the media are not clear.
