A solid comprehension of the visual pathway is important in understanding and diagnosing the many pathologies that can have an effect on the way individuals perceive the world around them. Beginning with the retina and progressing through to the visual cortex of the brain, this literature review traces the distribution and flow of nerve fibers within the visual pathway as they are currently understood. The Field Defects Model, a representation of this pathway, demonstrates how various lesions or disturbances in the pathway can affect the perceived visual field. This paper and model were developed as training aids to effectively assist optometric students in gaining a thorough understanding of this most important pathway of vision.
