Ocular tumors

Abstract

Intraocular tumors may leave the globe through vascular, neural, and transscleral routes and invade the periocular tissues and the orbit. These tumors primarily include retinoblastoma, uveal melanoma, and, to a lesser extent, malignant medulloepithelioma, retinal pigment epithelium carcinoma, and optic disk melanocytoma. The secondary involvement of orbital soft tissues with malignant ocular tumors is a rare condition, and the only clinically significant lesions in this group are the retinoblastoma and choroidal melanoma; therefore, only these tumors are discussed in this chapter.
