fundus

This is another way of saying retina.  The fundus describes the back portion of the retina that is visible using the eye microscope.  For example, doctors use a “fundus camera” to take pictures of the retina.  Fundus is a Latin term that means ‘bottom’ and is used to describe organ parts that look like the inside of a bowl. There is also a ‘fundus’ in the stomach, bladder, and in the uterus.
