  • describe the structure of the retinal nerve fiber layer

  • list the major components of the visual pathway
   
 

Section 2:

 Visual Field Defects as they relate to the Pathways
   
 

Description of content:  This section discusses what types of visual field defects can be expected as a result of damage to various points only the visual pathways.

 

Instructional objectives:  Upon completion of this section,  the student should be able to:

  • identify appropriate terminology for various types of field defects

  • name the general location along the pathway related to particular types of field defects
   
 

Section 3:

 Types of Visual Field Defects
