Ocular Involvement by Metastatic Breast Cancer: A Case Series and Review of Literature

Ocular metastasis from breast cancer can localize within the extraocular muscles and the orbital fat, bone, conjunctiva and eyelids. Choroid is the primary ocular site for metastatic cancer due to its rich vascular supply and fenestrated choriocapillaries. The most common presenting complaints are visual field defects, blurred vision, and floaters. We present a case series of three patients who were treated for early-stage breast cancer and later presented with ocular metastatic disease either as isolated metastatic lesion or as part of disseminated disease.
