title: [Results of A-scan echography in diseases of the orbit].
abstract: Standard A-scan sonography was performed in 191 patients with orbital mass lesions. In 36 cases tissue differentiation was not possible; in a further 11 patients the orbital lesion was not detected by ultrasonography. However, it provided an accurate histological diagnosis preoperatively in 87% of the remaining 144 patients.
