title: [Orbital metastasis].
abstract: OBJECTIVE
  The purpose of this paper is to present our data and to provide some conclusions about the attitude that has to be chosen when metastasis of the orbit is suspected.
  
  
  METHODS
  Between 1965 and 1994, 571 patients with non-traumatic orbital diseases were controlled in the department of ophthalmology of Lausanne. Thirty-four cases of metastasis of the orbit were selected, that is 24 females and 10 males, aged from 1 to 81 years. Tumors of the breast are the most frequent origin of this metastasis, followed by cutaneous melanomas and pulmonary tumors. Orbital metastasis was the first sign of a malignant process in 7 patients. The histologic diagnosis was confirmed in 15 patients. The type of treatment is presented herein and the follow-up of more than half of the cases is given.
  
  
  CONCLUSIONS
  Orbital metastasis can develop after a long time in patients who were previously treated for malignant tumors. In several cases, orbital metastasis was the first sign of a malignant process which starts to become general. This diagnosis has to be taken into account when a patient was treated earlier for a malignant tumor, and it is reasonable to propose a biopsy or an excision biopsy in every orbital pathology which was not confirmed by clinical or paraclinical investigations.
