Cysticercosis of the levator palpebrae superioris.

Fig. 1A. Complete ptosis of the right eye at presentation. Dear Editor, Cysticercosis cellulosae, the larval form of the pork tapeworm Taenia solium, causes cysticercosis, in which humans serve as the intermediate hosts in the parasite life cycle. Cysticercosis is endemic in developing regions such as South America, India and China.1,2 However, a rise in a cysticercosis has been observed in industrialised regions, owing to changing migration and travel patterns in recent years.3 Ophthalmic cysticercosis involving the vitreous, subretinal, subconjunctival and orbit have been reported previously. In this report, we describe a patient with myocysticercosis of the levator palpebrae superioris (LPS), a rare clinical entity with only 5 other cases in the literature.4,5 Case Report A 23-year-old Indian man presented with 2 weeks of right eye ptosis noticed incidentally on awakening. There was mild upper eyelid discomfort but no diplopia or decreased vision. His ophthalmic and medical histories were unremarkable. The patient was a construction worker and had previously lived in India. His visual acuity was 20/30 and 20/20 in the right and left eyes respectively. Both pupils were symmetric and reactive to light with no relative afferent pupillary defect; colour vision was normal. There was complete ptosis of the right eye with maximum levator function of 3 mm; maximum levator function in the left eye was 13 mm (Fig. 1A). No lid erythema or edema was present. Extraocular movements were full in
