Chapter 6—Visual system

Table 6.1 Disorders of visual acuity

Disorders such as nystagmus, conjunctivitis, impaired colour vision, night blindness and glaucoma (without visual loss) are usually binocular and cause minimal impairment. An assessment of 0 to 5% is appropriate for such conditions.

Visual field defects should be accurately mapped and assessed in accordance with the procedures dictated in AMA2.

Impairment is based on corrected visual acuity.

Chapter 7—Ear, nose and throat disorders

Table 7.1  Hearing

Hearing defects are assessed in accordance with the current procedures from Australian Hearing Services (Hearing Australia).

Once the binaural percentage loss of hearing has been calculated, it is then converted to a WPI value.

The calculation for converting the percentage loss of hearing to a WPI rating is:
