Ptosis due to parasitic infestation.

I read the recent article by Basu et al(1) with a great interest. The authors described an interesting case of ocular cysticercosis manifesting with ptosis. Indeed, ocular cysticercosis is not a rare disease in the developing countries, and ptosis due to cysticercosis is sporadically reported. Sekhar et al reported that subconjunctival cyst might be related to ptosis and suggested that the surgical removal of the parasite is a good management.(2) However, there are also other parasitic infestations that can induce ptosis. Echinococcosis (3) and trichuriasis(4) are the two widely mentioned parasitic infestations that can induce ptosis.
