Human vision and function
This subject introduces you to the human visual system from the eye to the cortex. Normal function is presented by explaining characteristics of light as an electromagnetic energy spectrum; the anatomy and physiology of the eye; visual pathways to the brain, vision (including colour vision and 3D perception). The subject will enable you to identify and understand the five major eye diseases affecting populations globally (Refractive error (the need for corrective lenses/glasses), cataract, diabetic eye disease, glaucoma and age-related macular degeneration). Patient case scenarios will be used to help you understand the medical (drug) and surgical treatment and management of these diseases.
