[Ultrasonic diagnosis of intraocular cysticercus].

Intraocular cysticerci are mostly located in the subretinal space or vitreous. When the fundus is obscured by exudate or hemorrhage, the diagnosis becomes very difficult with the ophthalmoscope or biomicroscope. The authors performed A- and B-scan echographic studies on 20 cases of intraocular cysticercus during February 1985 to December 1988; it was found that B-scan was very useful in diagnosing intraocular cysticercus with regard to its location and relation to surrounding tissues. Several cases with typical echograms are presented with discussions. The ultrasonic diagnoses were confirmed by surgery.
