[Metastasis from the colon to the choroid (author's transl)].

Various investigators have concluded that metastatic carcinoma is the most common malignant tumor of the eye. In about 70% of all cases the primary site is breast or lung. Metastasis from the colon to the choroid is found very seldom. The clinical course in our case is described and the elevated fashion of the right eye's metastatic carcinoma is shown. Usually cancerous tissue in the choroid spreads and produces a rather flat, diffuse lesion. Problems in making the diagnose are discussed. In choroidal metastasis radiation should be attempted, for adequate vision can sometimes be maintained for the remaining time of the patient's life.
