Metastatic Carcinoma to the Retina

Abstract

Two cases of metastatic carcinoma to the neuroretina are reported. One patient had an oat cell carcinoma of the lung that was metastatic to the brain and retina; this was confirmed postmortem. The other patient had metastatic breast carcinoma with seeding of tumor cells into the vitreous from a focus of retinal embolism. The diagnosis was confirmed from a vitrectomy specimen.
