[Selected cases of metastatic tumors to the visual system]

Metastases are always bad prognostic symptoms. They occur rather rarely, but may involve each element of visual system uni- or bilaterally. Usually we found these metastatic tumors in patients with earlier diagnosed neoplastic disease, in various tissues and organs. Therefore, in majority of cases treatment is only palliative, especially in those with the only eye or when the process is bilateral.
