[Subretinal cysticercosis].

This paper communicates the history of a case of subretinal cysticercosis in the left eye of a 73-year-old female patient. The only subjective complaints were slightly blurred vision in the affected eye. Serological findings in the blood (Agar-Gel precipitation; IFAT; ELISA) and the aqueous humor were negative. However, according to the literature false-negative serological findings are not uncommon. A stool examination for worm eggs or tapeworm segments was also negative. The remaining lab findings, including hemogram and immunoelectrophoresis, were also normal. Neurocysticercosis was ruled out by clinical and roentgenologic (CCT) diagnosis. As the patient declined treatment with praziquantel, a modern treatment for tapeworm, photocoagulation of the cysticercus was performed at two sittings, first peripheral demarcation and subsequently central coagulation.
