ABSTRACT

In ophthalmology, the eye is divided into two main segments—the anterior segment and the posterior segment. The anterior segment covers the entire front portion of the eye and mainly includes the areas of the eye one can see in the mirror, including the iris, conjunctiva, and lens. The posterior segment is the portion of the eye behind the lens, and it primarily refers to the retina, the inner neural lining of the eye, but also includes the vitreous humor, choroid and optic nerve. Posterior segment imaging refers to imaging these structures. One of the original methods of imaging the posterior segment is called fundus imaging, or fundus photography, and it is typically performed in an ophthalmologist's office. Fundus imaging is also performed at some optometrist's offices. Fundus imaging specifically refers to the retina or lining of the eye. The fundus camera is the original photographic device used in an ophthalmology environment to document the appearance of the retina.
