NFI distribution in normal and glaucoma subjects (N=152)
|A superior diagnostic tool – Nerve Fiber Indicator (NFI)|
A superior diagnostic tool – Nerve Fiber Indicator (NFI)
|95% of the normal eyes had an NFI ≤ 35 for ECC. VCC has similar performance. (CZM study, data on file.)|
- An artificial intelligence algorithm based on the entire RNFL profile.
- Though not definitive, the NFI is a single ordinal number indicating likelihood that the polarimetric retinal nerve fiber layer is normal.
- Proven performance in assessing early glaucoma.1,2
- The NFI is not intended to be used as the sole basis of diagnosis for disease.
