A rare case of giant subretinal migration of cysticercosis cyst with extensive epiretinal membrane and subretinal fibrosis

Cysticercosis is caused by cysticercus cellulosae, the larval form of pork tapeworm. In intraocular cysticercosis the cyst enters the subretinal space via the choroid and then gains entry into the vitreous cavity by piercing the retina. It is well established that the cyst can incite extensive intraocular inflammation. Other complications such as epiretinal membrane and cataract have been reported in the literature. Thus far, epiretinal membrane in intraocular cysticercosis has been reported at the site of entry of the cyst into the vitreous cavity. The data on the extent of epiretinal membrane is sparse. We report a rare case of migrating subretinal cysticercosis with extensive epiretinal membrane and subretinal fibrosis.
