◄Topic 2: Tear Drainage System

  • Introduction:


    The skull is a fascinating jigsaw puzzle of irregular bones. The Orbit, a substructure of the skull, is possibly the most intricate component of this puzzle.

    The orbit both supports and protects the eye. Additionally it's many holes, bumps, and grooves provide safe passage and sturdy attachment points for blood vessels, nerves, and muscles that move the eye.

    In this section, we'll examine the orbit when it's healthy and when it's harboring illness. Starting first with anatomy we'll review the basic structures and familiarize ourselves with how the eye sits in the head. After that we'll turn to cellulitis to better understand how infections of the skin can make their way into the orbit traveling posteriorly and even leading to infections of the brain and sinuses.

    While the eyeball itself gets the majority of attention when we study ophthalmology, the orbit and other supporting structures play essential roles in helping you see the world in front of you.
