Choroidal Metastasis

Choroidal metastases are tumors that began in another part of the body and spread to the vascular layer of the eye, the choroid, via the bloodstream. The majority of patients who develop metastatic cancer cells in the eye already know that they have cancer, but about ¼ of the time we learn about the underlying cancer only after the metastatic cancer in the eye is discovered. In the United States, the most common cause of choroidal metastases in men is lung cancer and in women is breast cancer.

Choroidal metastases are distinguished from other tumors of the choroid using various specialized imaging equipment such as ultrasound, ophthalmic photographs, optical coherence topography (OCT), fluorescein angiography, and other forms of testing, as well as a detailed clinical examination.

Treatment of choroidal metastases consists of external beam radiation, plaque therapy, and/or chemotherapy, depending on many factors specific to the patient’s situation.
