Bilateral metastasis to optic nerve head – Interesting case report series

Abstract

Most intraocular metastatic tumors occur in the uveal tract, while isolated metastasis to the optic nerve is rarely found. Breast and lung cancers are the tumor types metastasizing to the eye most frequently; however, metastases of prostate cancer, melanoma, gastrointestinal tract, and renal tumors have also been reported. We describe three rare cases of optic nerve metastasis from primary carcinoma in brain, bone, and ano-rectum, which were not found in the literature previously. Bilateral optic disc edema in a patient with primary tumor elsewhere should be evaluated completely to rule out metastasis.
