| name | Deprecated Visual acuity.binocular Eye Autorefractor.man | ||
| description | The relative ability of the visual organ to resolve detail that is usually expressed as the reciprocal of the minimum angular separation in minutes of two lines just resolvable as separate and that forms in the average human eye an angle of one minute. | ||
| status | DEPRECATED | ||
| status reason | Erroneous - Auto refractors do not measure visual acuity; they measure refraction error, which is a combination of cylinder, sphere and axis. | ||
Fully-Specified Name | |||
| component | Visual acuity.binocular | ||
| property | LenRto = Length Ratio | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Eye | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range.
