Orbital Anatomy

Abstract

The orbit is defined as a bony cavity that harbors the globe and supporting muscular, vascular, and nervous structures. Due to the fact that the orbit comprises a finite space, even small processes such as seen with infection and tumors can cause large disruptions in local anatomy resulting in mechanical and visual dysfunction. In-depth knowledge of orbital anatomy is required to understand the consequences of various orbital pathology and surgical treatment. This chapter will provide a broad overview of the anatomy of the orbit and its surrounding structures and will also highlight key clinical relevance.
