Results: It was found that a simulated LVA of ~0.2 (decimal acuity; Snellen 6/30 or 20/100, LogMAR 0.7) had a negative impact on test performance for the Trail Making Test, Complex Figure of Rey (copy score), and Visual Object and Space Perception battery subtest 3, but not for the...
Test-retest reliability was high (r = 0.82), with 93% of retest scores within 0.1 logMAR unit of the initial test score. The 95% confidence interval for an acuity score was calculated to be the score ±0.125 logMAR unit. For a change between 2 acuity scores, the 95% confidence interval...
If the child did not show clear evidence of resolving that grating, coarser gratings were presented, until the tester confirmed the finest grating that the child could resolve; this was recorded as the grating acuity score for that eye. Grating acuity results were log-transformed prior to ...

As letter size changes by 0.1logMAR units per row and there are five letters in each row,each letter can be assigned a score of 0.02.The final score can therefore take account of every letter that ha been read correctly and the test should continue until half of the letters on a line ...
Test Modes: 1. Manual. 2. Auto scoring In Auto scoring, you use the swiping gestures to indicate correct readings or wrong readings, and the app calculates the score. Through enabling “Record Scores” in Settings, you can keep track of the progression of your visual acuity. Visual acuity ...
The result of a visual acuity test should be reported as a log-MAR value (log of the minimum angle of resolution). Normal visual acuity for most adults is approximately −0.1 on this scale, which is equivalent to 20/16 on a Snellen visual acuity chart. A two-line or greater change ...
VA measurements can be scored in logMAR notation, using the visual acuity rating (VAR) score or converting scores to an equivalent Snellen value. Computer-based systems will typically convert VA values for you. LogMAR or VAR could be used on your own record cards. However, equivalent Snellen ...
The smartphone-based visual acuity test may be of potential benefit in remote or self-administered visual acuity testing. This technology has a significant impact on practice in terms of remote health monitoring, which may reduce patient stress, increase patient empowerment, and reduce overall costs,...
