nameLeft eye Dark-mediated rod adaptation time
descriptionThis term was created for, but is not limited in use to, the Rod Intercept™ (RI™) as measured by the AdaptDx®. Rod Intercept™ is the duration between exposure to a bright light (photo bleaching using a flash) and recovery of a visual sensitivity by the eye's rod photoreceptors to a threshold of 3.0 log units of attenuation of the stimulus. The rod-intercept time is used to quantify rod-mediated dark adaptation (DA), and slower DA is associated with the early phases of age-related macular degeneration (AMD).

componentDark-mediated rod adaptation time
propertyTime  =  Time Duration
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemEye.left
scaleQn  =  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. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
