Abstract
The purpose was determinate reliability test retest and concordance between clinical techniques that measure amplitude of accommodation. Methods: seventy nine students who had normal visual function, refractive and accommodative skills participated. The techniques were: minus lens (near), minus lens (far) and push down modified (-4.00D lens). Results: Intraclass Correlation Coefficient (ICC) show that test retest was high three techniques (>0,7); Concordance correlation coefficient of Lin (ρc) showed that agreement was poor for all of them (ρc≤0,9). Limits of agreement (95%) were push down modified +/-1,22; minus lens near +/-2,02; minus lens far +/- 3,44. Conclusion: reliability test retest was higher for push down modified and concordance between the techniques was poor so, these are not interchangeable.
