“…15 This case had been referred to them for identification and was published twice in 1962. 16,17 In the same year, Deweese and others 18 and Rentorff and others 19 reported an L. serrata nymph in the anterior chamber of the eye of an eight-year-old girl from Mississippi. The third case was reported in Israel by Lang and others 20 and involved a 12-year-old girl presenting with unilateral glaucoma secondary to the iritis caused by an L. serrata larva.…”

Abstract. Linguatula serrata is a pentastomid, a cosmopolitan parasite belonging to the Phylum Pentastomida. Humans may act as an intermediate or accidental definitive host of this parasite, manifesting the nasopharyngeal or visceral form, with the latter having been described more frequently. The occurrence of ocular linguatuliasis is extremely rare, but it has been reported in the United States and Israel. The objective of the present paper was to report the first case of ocular linguatuliasis in Ecuador and to extend the morphologic study of L. serrata by morphometric analysis. The patient studied was a 34-year old woman from Guayaquil, Ecuador who complained of ocular pain with conjunctivitis and visual difficulties of two-months duration. Biomicroscopic examination revealed a mobile body in the anterior chamber of the eye. The mobile body was surgically removed. The specimen was fixed in alcohol, cleared using the technique of Loos, stained with acetic carmine, and mounted on balsam between a slide and a coverslip. It was observed with stereoscopic and common light microscopes in combination with an automatic system for image analysis and processing. The morphologic and morphometric characteristics corresponded to the third-instar larval form of L. serrata. To our knowledge, ocular linguatuliasis has not been previously described in South America, with this being the first report for Ecuador and South America. The present study shows that computer morphometry can adequately contribute both to the morphologic study and to the systematic classification of Pentastomids, and L. serrata in particular.

“…Humans can also serve as accidental intermediate hosts, when ingesting the eggs (visceral infection) ( 3 ). Intraocular infection is extremely rare; only 5 cases caused by L. serrata tongue worms have been described: 2 from the southern United States ( 4 – 5 ), 1 from Portugal ( 6 ), 1 from Israel ( 7 ), and 1 from Ecuador ( 8 ). …”

We report a case of intraocular Linguatula in healthy young female who presented with a history of trivial trauma, dislocated lens, inflammation and secondary glaucoma. A mobile worm was seen in the anterior chamber. Pars plana lensectomy and vitrectomy was planned to remove both the cataractous lens and the parasite during which the worm disappeared from view but was later recovered from the cassette fluid. It was identified as the nymphal form of Linguatula serrata (tongue worm).
