title: [Characterize the differences between anisometropic amblyopes and normal people when discriminating different pictures under various degrees of Gauss noises].
abstract: OBJECTIVE
  To observe the differences between anisometropic amblyopes and normal people when all of them were asked to discriminate those topological and non-topological pictures embedded in Gauss noises.
  
  
  METHODS
  Stimulus pictures (noise variance were 0.04, 0.08, 0.12 respectively) were run using Matlab software, the error ratios of identification of amblyopia groups and control groups were recorded.
  
  
  RESULTS
  The P-values of anisometropic amblyopes were 0.06 (closure pictures) and 0.088 (disclosure pictures) under the different experimental lasting time. No matter whenever the experimental lasting time and whatever the characteristics of the pictures, the error ratios of identification of amblyopia groups were higher than that of control groups, except for closure pictures at 5 s.
  
  
  CONCLUSIONS
  The capabilities of amblyopes when discriminate the different pictures were lower than that of normal groups. We found that different outcomes of amblyopia groups were caused by their own perception defect.
