Human Ocular Thelaziasis: A Case Report from Indonesia

Abstract

Thelaziasis is a parasitic disease caused by a nematode of genus Thelazia, which is rare in the world, including Indonesia. The definitive hosts for Thelazia are canids, felids, mustelids, and other mammals, while the vector is drosophila flies. Consequently, this study reported an uncommon occurrence of human ocular thelaziasis in Indonesia. Based on the patient's complaints and physical examination, we found a living worm that move actively in the anterior chamber; then documentation is carried out both during the examination at the polyclinic and in the operating room. The surgery was performed using topical anaesthesia, clear corneal incision, and removing worm through the main port. Morphological examination from the parasitology laboratory showed that the worm was Thelazia callipaeda species. Following this intervention, the patient was given an oral anti-helminthics drug, topical and oral antibiotics, topical steroid, and surgical treatment. There was no recurrence or appearance of any other symptoms reported in 2 months of follow-up.
