PURPOSE To evaluate the usefulness of USG-CD in the assessment of ocular and orbital tumors in children. METHODS 24 children with focal changes in eyeballs and orbita were examined. The results of USG-CD were compared with those of computer tomography and angiography. Diagnosis was confirmed during surgery or by biopsy. RESULTS Typical USG-CD pictures of haemangioma, melanoma, retinoblastoma and also pseudotumors caused by haematoma and inflammation were described. The sonographic examination enabled to determine the placement and extent of the lesions, the Doppler option allowed to evaluate their blood-supply and in some cases, e.g. in haemangioma, to state a diagnosis.
