Anatomy of the eye and the healthy fundus

The human eye is an intricate and widely used major sense organ of the body, and has been commonly likened to a camera. Broadly it can be divided into two main segments—the anterior segment and the posterior segment. Understanding the basic anatomy of the human eye is a requirement for all health-care providers, but sound knowledge is of paramount importance to those involved in eye screening. This chapter describes and includes pictorial emphasis of the anatomy of the eye, and more specifically, the human retina and its structure and function. The detail provided here is limited, but relevant to those involved in eye screening. A more in-depth and comprehensive discussion of the anatomy of the eye is beyond the scope of this book and, therefore, further reading is recommended.
