to the nearest multiple of 5. This is known as the combined monocular impairment rating for that eye.

 Step 5: Combine the two combined monocular impairment ratings obtained in
Step 4 by applying Table 8.1.3.

 Binocular impairment rating

 After a combined monocular impairment rating has been made for each eye, the two ratings are to be combined by applying Table 8.1.3. The value obtained is known as the binocular impairment rating.

Only one criterion may be selected from this table. If the accepted condition satis­ fies more than one criterion, the criterion resulting in the higher rating is to be chosen. The single rating is then included in both monocular assessments.

No age adjustment permitted for this table

The combined monocular impairment ratings obtained in Step 4 are those values found in the shaded area of Table 8.1.3. The values for the better and worse eye are to be taken from the values in the shaded regions along the horizontal and vertical axes respectively.

    For convenience, Table 8.1.3 incorporates Table 8.1.1 along both its axes. The figures in italics give the possible losses of visual acuity. The values in the shaded area immediately beside or above the figures in italics give the corresponding monocular assessment.

    If the only condition affecting visual function is decreased visual acuity, the visual acuities for the better and the worse eye respectively can be read from the values in italics along the horizontal and vertical axes respectively.

    Paired organs policy

    If an accepted condition affects one eye only, the paired organs policy may apply
(see Chapter 21).
