Malignancies with a tendency to metastasize to the eyelid or ocular structures.

Metastatic tumors to the eye and eyelid are generally seen in patients with disseminated metastases in the setting of advanced disease. Occasionally, they can present as the first sign of occult malignancy. The choroid is the most common site of intraocular metastases secondary to its dense vascular supply. Similar to the eye, metastatic tumors to the eyelid can present with variety of clinical findings and are most often seen in patients with known history of cancer. The most common skin malignancy that can spread to ocular structures is cutaneous melanoma, whereas the most common non-cutaneous malignancy is breast cancer followed by lung cancer. In pediatric patients, metastatic disease to the eye is rare and can be seen in neuroblastoma and Ewing sarcoma. The overall prognosis of metastatic lesions involving the eye and eyelid is typically poor with a mean survival of months. Ophthalmologists play an important role in the diagnosis of metastatic disease of the eye and eyelid; therefore, it is imperative for patients to undergo a complete ophthalmic exam and systemic work up if they have new onset vision changes and a known history of cancer. Early diagnosis and management with systemic and local therapies can maximize quality of life and preserve vision.
