Worms mate in man's eyes, get plucked out right before larvae burst out

Key points

• Doctors removed a set of adult worms from a man's eyes, ending his infection without the need for antiparasitic medication. The worms spread through flies that feed on tears and secretions from infected eyes.
• Flies carry the larvae from one eye to another, where the larvae mature and mate. Female worms release coiled larvae that burst out of the flies after they were pulled from the man's eyes.
• At a follow-up two months later, all of his eye symptoms had resolved and no worms remained.
