  1. P1: expresses in percentage the number of fixation points that are within the area of a circle with 1-degree diameter. 95% BCEA (Bivariate Contour Ellipse Area) value establishes the ellipse area, expressed in square degrees, comprising 95% of the fixations points used by the patient during the test
  2. * Average retinal sensitivity threshold in decibels
