Abstract

An 80-year-old male reported to the clinic with complaints of diminished vision, foreign body sensation, and occasionally some black object moving in front of the right eye. Detailed ocular examination revealed three slender creamy white live worms in the conjunctival sac of the right eye. Total three worms were retrieved and sent to the pathology department for detailed examination. The worm was identified as gravid Thelazia callipaeda. As per the search results in PubMed and Cochrane search engine, this is the first report of human case of gravid Thelazia infestation with simultaneous existence of embryonated or ensheathed eggs and primary-stage larvae in the same worm.
