  1. BCVA best-corrected visual acuity, CDR cup-to-disc ratio, D diopters, HM hand motion, IOP intraocular pressure, LP light perception, MD mean deviation, SE spherical equivalent
  2. aThe average CDR is the square root of the ratio of the area of the cup to the area of the disc
  3. bThe vertical CDR is the ratio of vertical cup diameter to vertical disc diameter
