Sec. 4.77  Examination of muscle function.

    The measurement of muscle function will be undertaken only when the 
history and findings reflect disease or injury of the extrinsic muscles 
of the eye, or of the motor nerves supplying these muscles. The 
measurement will be performed using a Goldmann Perimeter Chart as in 
Figure 2 below. The chart identifies four major quadrants, (upward, 
downward, and two lateral) plus a central field (20[deg] or less). The 
examiner will chart the areas in which diplopia exists, and such plotted 
chart will be made a part of the examination report. Muscle function is 
considered normal (20/40) when diplopia does not exist within 40[deg] in 
the lateral or downward quadrants, or within 30[deg] in the upward 
quadrant. Impairment of muscle function is to be supported in each 
instance by record of actual appropriate pathology. Diplopia which is 
only occasional or correctable is not considered a disability.
