Cup Diameter to Disc Diameter Ratio Estimates
Estimates are made verically along an imaginary line drawn
from the 12:00 to 6:00 position through the center of the disc.
Normal optic nerve
with small cup
Cup-to-disc ratio is .2
Low level of
glaucoma suspicion
Moderately advanced
cupping
Cup-to disc ratio is .7
Neural rim is present
but startin to thin
Moderate level of
glaucoma suspicion
Almost total cup with
cup-to-disc ratio of .9
Neural rim is very thin but
present. Note peripapillary
chorioretinal atrophy
superiorly, easily confused
with true disc tissue.
High level of
glaucoma suspicion

Other historical variables such as high myopia or hyperopia, systemic hypertension, steroid use, and perhaps diabetes ar not strong enough to be assigned a weight, but may be considered in the overall assessment of glaucoma risk.
Level of Glaucoma Risk Weighting Score
High 4 or greater
Moderate 3
Low 2 or less
Add weighted scores to determine risk level.
