Systemic Tumors and Retina

The eyes are a rare site for systemic metastasis. Metastatic tumors of the eye are more common than primary ocular tumors. The choroid is the most common site for ocular metastases whereas retinal metastases are relatively rare. The retina metastasis of Malignant melanoma, pulmonary carcinoma, breast adenocarcinoma, gastrointestinal carcinoma, uterine adenocarcinoma, and lymphoma was reported. Retinal metastases may cause visual symptoms in patients as well as be asymptomatic. Retinal hemorrhage, retinal mass, retinal or vitreous seeding, vascular occlusion, vitreous hemorrhage, and retinal detachment may be seen due to retinal metastasis. The ocular findings of systemic tumors metastasize to the retina and the approach to the patient are discussed in this review.
