Abstract

Extra-lymphatic manifestation of filariasis is uncommon and may usually be clinically misdiagnosed. The extra lymphatic presentation of Brugia malayi may due to the site of entry of the infective larvae, and only a few cases have been proven for the causative species. We report here a 59-year-old woman presented with swollen right conjunctiva and complaint of migratory swelling at her eyelid, which has turned out to be ocular filariasis by B. malayi in Chantaburi province, Thailand. This report highlights the increasing cases of B. malayi as a causative agent of ocular filariasis in human.

Keywords: Brugia malayi; Mitochondrial 12S rRNA; Ocular filariasis; Sequencing.
