Video

Representative video showing Oestrus ovis larvae in patient with acute external ophthalmomyiasis caused by Oestrus ovis infection after sheep exposure during Eid al-Adha, Algeria, 2025. Larvae exhibit rapid, active motility and wriggling along the surface of the inferior conjunctival fornix and on the corneal surface. The smooth corneal epithelium appeared to reduce their locomotor velocity.
