Tumours of the orbit diagnosed by fine needle biopsy

Fine needle aspiration biopsies were used for the diagnosis of orbital tumours. Examples of benign and malignant primary and metastatic orbital neoplasms, as well as inflammatory lesions diagnosed in this way are described. The method has proved of great value. This was specially true for processes located posteriorly in the orbit. The necessity for close cooperation between the ophthalmological and clinical cytological departments is emphasized.
