title: Motion perception of short-wavelength sensitive cones in glaucoma using random dots moving.
abstract: OBJECTIVE
  To determine whether motion perception of short-wavelength sensitive(SWS) cones is capable of predicting primary open angle glaucoma(POAG) optic neuropathy.
  
  
  METHODS
  Motion perceptions of SWS cones were isolated by Blue random dot stimulus displayed on the Yellow background, then the detecting displacement threshold of motion perception from SWS cone in POAG was measured, and compared with the age-matched normal group.
  
  
  RESULTS
  The detecting displacement thresholds of motion perception from SWS cones in 8 sites of 15 degrees were all elevated in POAG compared with the normal group.
  
  
  CONCLUSIONS
  These findings suggest that motion perception of SWS cones may reveal preclinical visual nerve damage in early POAG.
