public class DecimalVisualAcuity
extends AbstractDataElementWrapper
implements FloatingPointDoubleWrapper

Name: Decimal Visual Acuity
Keyword: DecimalVisualAcuity
Tag: (0046,0137)
Value Representation: FD
Value Multiplicity: 1

• Described in the contexts:
  • Visual Acuity Measurements Macro > Decimal Visual Acuity
  as follows:
  Attribute Name: Decimal Visual Acuity
  Type: 1
  Attribute Description:

  A patient's visual acuity specified in decimal. The value is derived from two values in a fraction where the numerator of the fraction is the nominal distance to the chart that the patient is reading. The denominator represents the line of smallest optotypes of which the patient can see more than half.

  Note

  1. Typical examples: reference standard is 1, severe vision loss is 0.1

  2. See chapterRR for guidance in converting Decimal Visual Acuity to other customarily used display notation such as 20/20 in the US and 6/6 in Britain.
