[Orbital apex syndrome in a child with Wegener's granulomatosis].

The authors report the case of a 10 year-old child presenting with orbital apex syndrome as the initial manifestation of Wegener's granulomatosis. Orbital apex syndrome is characterized by complete or partial paralysis of the third, fourth and sixth cranial nerves with involvement of the trigeminal nerve's ophthalmic branch. The different mechanisms responsible for ocular complications in Wegener's granulomatosis and the usefulness of computer assisted tomography in this clinical situation are discussed.
