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
^aThe average CDR is the square root of the ratio of the area of the cup to the area of the disc
^bThe vertical CDR is the ratio of vertical cup diameter to vertical disc diameter
