Abstract;Purpose: To investigate the influence of axial length on white-on-white (W-on-W) perimetry and blue-on-yellow (B-on-Y) perimetry in myopic subjects according to the presence or absence of peripapillary chorioretinal atrophy (PPA). Materials and methods: Both B-on-Y and W-on-W perimetry were performed on 64 normal volunteers whose fundus photography was clear, and the presence or absence of PPA was distinct. We divided the 64 normal volunteers into a PPA group and a no-PPA group, and investigated the influence of axial length on both types of perimetry. Results: As axial length extended in all cases and in the PPA group, mean deviation (MD) decreased significantly in both B-on-Y and W-on-W perimetry. There was no significant difference in the no-PPA group. In the PPA group, the retinal sensitivity decreased significantly at 22 test points in B-on-Y, as axial length extended; and this decrease occurred at 12 test points in W-on-W perimetry. These points were located mainly around the Mariotte blind spot, central points, and the area of Bjerrum. In the no-PPA group, the retinal sensitivity decreased significantly at only two test points in B-on-Y perimetry, but no decrease occurred at these test points in W-on-W perimetry. Conclusions: We should consider the presence of PPA and the influence of axial length in the interpretation of the results of W-on-W and B-on-Y perimetry. (author abst.)
