Case of Filaria loa

A clinician describes a patient who, after prolonged residence in West Africa and episodic fever, experienced a motile parasitic worm intermittently roaming beneath the conjunctiva and in the eyelids, more active in warmth and causing transient irritation, tearing, and redness. Careful examination, topical anaesthesia, and a conjunctival incision permitted surgical extraction without subsequent inflammation. The removed specimen, measured and examined microscopically, displayed a tapered extremity and an extruded alimentary canal after handling; it was preserved and mounted for further pathological study. The account focuses on clinical presentation, operative technique, parasite morphology, and specimen preparation.
