title: [Clinical characteristics of choroidal metastasis].
abstract: BACKGROUND
  Choroidal metastasis (CM) is the most common malignant intraocular tumor. The aim of this study was the characterization of the ophthalmoscopic aspect, the underlying tumor disease and differential diagnosis of this entity.
  
  
  METHODS
  Retrospective observational case series.
  
  
  METHODS
  A total of 71 consecutive patients with CM were evaluated. Special attention was given to ocular symptoms, the ophthalmoscopic and sonographic aspects and the characteristics of the underlying tumor disease. All patients had undergone screening (CCT, CT of thorax and abdomen; bone scintigraphy) for the primary tumor and further organ metastases.
  
  
  RESULTS
  Of the patients 95% had symptomatic CM, in 5% of the patients CM was detected by chance, 60% had a single CM, 40% showed multiple (2-14) lesions and 18% ( n=13) had no history of tumor disease. In 12 of these patients lung cancer could be diagnosed. In 53% of the patients the primary tumor was breast cancer, in 26% lung cancer, in 3% kidney cancer, bowel cancer, choroidal or cutaneous melanoma and in single patients cervical, ovarian, thymus or prostate cancer. In one patient who died from disseminated metastases, no definite primary tumor could be detected. Of the patients 96% had further metastases, CM occurred with a mean interval after diagnosis of the primary of 9 months in lung cancer and 68 months in breast cancer. CM was the first clinical sign of tumor disease in 58% of patients with lung cancer and the first clinical sign of metastatic disease in 28% of patients with breast cancer.
  
  
  CONCLUSIONS
  Choroidal metastasis occurs almost exclusively in metastatic disease. In breast cancer it typically occurs years after diagnosis of the primary tumor and may be the first sign of metastatic disease. In lung cancer choroidal metastasis may be the first sign of the tumor disease.
