[Cryo- and photocoagulation for choroidal metastases of a thyroid carcinoma (author's transl)]

A 47-year-old patient underwent surgery in 1972 for a metastasising medullary thyroid carcinoma. 4 years later he developed choroidal metastases in the left eye and then, after another 3 months, multiple small metastases appeared in the right eye. The metastases were cryo- and photocoagulated because medullary thyroid carcinoma do not respond to radiation or chemotherapy. Although the single very large metastasis in the left eye was scarcely affected, the multiple metastases in the right eye were destroyed. As a result the patient has retained useful vision in this eye for the past three years.
