Color-Code Agreement Among Stratus, Cirrus, and Spectralis Optical Coherence Tomography in Relapsing-Remitting Multiple Sclerosis With and Without Prior Optic Neuritis

We found a substantial color-code disagreement among devices in patients with relapsing-remitting multiple sclerosis regarding the ON antecedent. In non-ON eyes, Spectralis yielded a significantly higher thinning for temporal quadrant than Cirrus, suggesting that N-site axonal analysis could define axonal damage in relapsing-remitting multiple sclerosis patients earlier than conventional RNFL analysis.
