Have the students discuss what kind of visual problems would occur if defects occurred at specific anatomic sites. Examples of anatomic sites, associated defects, and visual problems are given in the table: 
 
Anatomic Sites, Defects, & Visual Problems
Anatomic Site Defect Visual Problem
Right eye Damaged in accident
  1. Blind in right eye
  2. Loss of binocular vision (depth perception)
Left optic nerve Damaged by infection
  1. Blind in left eye
  2. Loss of binocular vision (depth perception )
Optic chiasm Pressure from pituitary tumor Temporal hemianopsia
