Ocular cysticercosis. A report of 13 cases.

Ocular cysticercosis does not usually present with signs of systemic involvement. Stool examination and eosinophil count are invariably negative, but computed tomography and agglutination tests are more commonly positive. This condition is more common in the vitreous cavity where it may cause diagnostic problems. Removal of the cyst is a standardised procedure, but the prognosis is poor because of severe ocular reaction to the cysts. Prevention of cysticercus infection is very important.
