title: [The influence on the static visual field of peripapillary chorioretinal atrophy--relation to refractive error].
abstract: OBJECTIVE
  To investigate the influence of refractive error on white-on-white perimetry(W-on-W) in myopic subjects according to the presence or absence of peripapillary chorioretinal atrophy (PPA).
  
  
  METHODS
  W-on-W perimetry was performed on 57 normal volunteers whose fundus photography was clear and the presence or absence of PPA was distinct. We divided the 57 normal volunteers into a PPA-positive group and a PPA-negative group, and investigated the influence of refractive error.
  
  
  RESULTS
  Mean deviation (MD) reduction was significantly correlated with the degree of myopia in the myopic group, whereas there was no significant correlation with refractive error in the control group. In the myopic group, MD reduction was significantly correlated with the degree of myopia in the PPA-positive group, whereas there was no significant correlation between refractive error and MD in the PPA-negative group. In the control group, there was no significant correlation between refractive error and MD in either the PPA-positive group or the PPA-negative group.
  
  
  CONCLUSIONS
  MD reduction was significantly correlated with the degree of myopia in myopic subjects, and was more remarkable in PPA-positive subjects.
