Choroidal Metastasis

Choroidal metastases usually develop late in the disease, and are more common in those with metastases to the lung or brain. Breast cancer is the most common cancer to metastasize to the choroid.

Choroidal metastases are typically yellow in color, and are associated with subretinal fluid. They are usually anatomically located between the macula and equator.

Symptoms include blurred vision, flashes, floaters, and pain.

Ultrasound can be very useful in diagnosis. An A-scan will typically show moderate to high internal reflectivity. A B-scan will identify an echogenic choroidal mass and may show secondary retinal detachment.
