[Traumatic injury of ciliary ganglion].

The authors report a case in which slight cranial trauma was followed by manifestations of damage to the right ciliary ganglion. After 3 weeks the signs of damage began to regress and disappeared completely. Laboratory investigations failed to demonstrate any abnormalities. Apart from this trauma there were no other detectable causes, and especially there were no history data suggesting past infection, botulism or syphilis. The mechanism of ciliary ganglion injury is not known (contusion, haematoma, oedema etc.).
