Introduction: Ocular involvement by cysticercosis is uncommon and rare in the anterior chamber with 10 reports in English literature. Case report: A 25-year-old male patient sought medical assistance reporting tumour growth in the left eye for one month. He presented normal visual acuity and, at slit-lamp examination, mild conjunctival erythema and a free-floating translucent cyst (measuring 0.5 mm in diameter) in the anterior chamber adherent to the iris. The patient was oriented to use topic steroid and return within three days. He returned three months later complaining of low visual acuity which was confirmed by examination {20/400}. He presented also ciliary injection, anterior chamber reaction and free-floating vesicle in the anterior chamber measuring 4 mm in diameter with autonomous movement (video). The vesicle tended to persist interposed to the visual axis and the intraocular pressure was elevated. The lesion was removed by a 6 mm scieral tunnel incision and viscoexpression. The microscopic analysis revealed an intact cyst of Cysticercus cellulosae. One week after surgery, visual acuity was 20/20 without correction and there were no inflammatory findings. Comments: Anterior chamber cysticercosis is rare and rapid surgical excision is essential to prevent glaucoma and anterior uveitis. The opted treatment was viscoexpression which has been shown to be successful in three previous reports. We used scieral tunnel assessment because of the requirement of incision greater than 3 mm. The technique employed in the present case allowed the excision of the intact vesicle without induction of astigmatism or extrusion of intracystic content and consequent uveitis.
