Cancers Affecting the Retina
Choroidal metastases
Choroidal metastases are common because the choroid is highly vascular. The most common primary cancers are those of the breast in women and of the lung and prostate in men. Symptoms tend to develop late and include loss of vision and symptoms of retinal detachment. Diagnosis is often incidental during routine ophthalmoscopy. Ultrasonography is usually done, and the diagnosis is confirmed using fine-needle biopsy. Treatment depends on the primary cancer and usually involves systemic chemotherapy, radiation therapy, or both.
