Is OCT a Viable Tool to Monitor Disease-Modifying Treatments in RRMS Yet?

Optical coherence tomography (OCT) is considered a key research tool to monitor neurodegenerative processes in CNS disorders. This is particularly applicable to multiple sclerosis (MS), in which retinal changes (peripapillary retinal nerve fiber layer and ganglion cell–inner plexiform layer [GCIPL] thicknesses) tend to reflect MRI markers of CNS damage and atrophy, especially in eyes not affected by previous optic neuritis.1
