153     See Figure 6-A for steps in deriving a visual system impairment rating. Use Table 6.1: Conversion of the visual system to WPI rating to convert a visual system impairment rating to a WPI rating.
    Figure 6-A: Steps for calculating impairment of the visual system
Step 1   Assess and record the percentage loss of central vision for each eye separately, combining the losses of near and distance vision. Refer to Figure 6-C: Percentage loss of central vision in one eye.
Step 2   Assess and record the percentage loss of visual fields for each eye separately (monocular) or for both eyes together (binocular).
Step 3   Using the combined values chart (see Appendix 1), combine the results from Step 1 and Step 2 for each eye if any central vision and visual field impairment is present.
Step 4   Assess and record the percentage loss of ocular motility.
Step 5   Using the combined values chart (see Appendix 1), combine the result of Step 3 with Step 4 if there is any ocular motility impairment.
Step 6   Assess and record the percentage loss if other ocular impairments are present.
Step 7   Using the combined values chart (see Appendix 1), combine the result of Step 5 with Step 6 if any other ocular impairment is present.
Step 8   Assess the visual impairment for both eyes. The visual impairment for both eyes is calculated by the formula:
         Alternatively use Figure 6-F: Calculation of visual system impairment for both eyes.
Step 9   Convert the visual impairment for both eyes to a WPI rating using Table 6.1: Conversion of the visual system to WPI rating.
Step 10  Using the combined values chart (see Appendix 1), combine the result of Step 9 with any impairment (up to 10% maximum) arising from other conditions causing permanent deformities (see Section 6.5 (Other conditions causing permanent deformities causing up to 10% impairment of the whole person)).
