[Unusual courses of orbit-floor-fracture (author's transl)].

Blunt trauma can lead to intra-orbital haemorrhage, which cause motility and sensibility disturbances typically found also in orbit-floor fracture. When there is also a fracture present, it can be problematic to give the function deficiencies their right causes. Spontaneous improvement of the defiencies can be expected in a reasonable percentage of cases. Operative revision therefore should not be performed in cases of doubt, or in any case not earlier than 14 days after the injury. In a severe stove-in orbit with enophthalmos and double vision the operation should be preformed within the first week. In some cases, however, residual diplopia can be expected in spite of optimal early therapy.
