title: [Orbital decompression (author's transl)].
abstract: Decompression of the orbit for retro-orbital haematoma is not usually performed. On the other hand it is recommended when ophthalmoscopy shows impending thrombosis secondary to a massive orbital haematoma. In such cases both surgical decompression of the orbit and splitting of the optic nerve sheath should be done. The indications for the surgical exposure of the optic canal are: 1. When there is progressive change on perimetry of the visual fields; 2. When there is radiological evidence of narrowing of the optic canal; 3. When there is papilloedema. Because of the magnitude of the surgery it is only rarely utilized, and a conservative management is most frequently better.
