Anaesthesia Fundamentals | Anatomy | Optic Pathways, Visual Fields, Motor and Sensory Innervation

Optic Pathways, Visual Fields, Motor and Sensory Innervation
Session Overview
Description
Applied anatomy of the nerve and blood supply of the eye. This session also covers basic optics.

Learning Objectives
By the end of this session you will be able to:

• List the nerves that transmit sensory information, provide sensation and autonomic innervation to the eye
• Describe the optical neural pathway
• Describe the neural pathway of the pupillary light reflex
• Identify the arterial supply and venous drainage of the eye
• Differentiate emmetropia from myopia, hypermetropia and presbyopia

To fully understand the workings of the eye, it is necessary to study the component parts of its nerve supply.

The sensation of vision, the incredibly fine control of ocular movement and clinically important reflexes depend on these nerves.

We need to know where the nerves are, and their functions.
Only then can we fully understand how regional eye blocks work.

In this session you will learn about the anatomy of the nerves and the blood supply of the eye.

You will also understand why some people need to wear glasses and how lenses are used to correct visual impairment.
