The results of this testing technique may apply to Listing 2.02 of appendix 1. Stimulation
of the retina changes the electrical activity of the cerebral cortex. A valid, absent
response to VER testing in an eye indicates that the best-corrected visual acuity
in that eye is 20/200 or less. Conversely, a normal response to VER testing is a significant
finding in the assessment of alleged reduction of visual acuity without demonstrable
cause. It is an improved technique because it can be used to evaluate individuals
who are unwilling or unable to cooperate in other techniques.
