Sec. 4.76  Examination of field vision.

    Measurement of the visual field will be made when there is disease 
of the optic nerve or when otherwise indicated. The usual perimetric 
methods will be employed, using a standard perimeter and 3 mm. white 
test object. At least 16 meridians 22\1/2\ degrees apart will be charted 
for each eye. (See Figure 1. For the 8 principal meridians, see table 
III.) The charts will be made a part of the report of examination. Not 
less than 2 recordings, and when possible, 3 will be made. The minimum 
limit for this function is established as a concentric central 
contraction of the visual field to 5[deg]. This type of contraction of 
the visual field reduces the visual efficiency to zero. Where available 
the examination for form field should be supplemented, when indicated, 
by the use of tangent screen or campimeter. This last test is especially 
valuable in detection of scotoma.
