Objective To quantify axonal loss in the retinal nerve fiber layer (RNFL) in patients with multiple sclerosis (MS), with and without a history of optic neuritis, by means of ocular imaging technologies. Methods This cross-sectional study enrolled 50 patients with MS and 25 age- and sex-matched healthy controls. All patients underwent neurologic assessment and a complete ophthalmic examination that included visual acuity, visual field examination, optical coherence tomography (OCT), scanning laser polarimetry (GDx) and visual evoked potentials (VEPs). Visual parameters and RNFL measurements were evaluated in MS eyes with a prior optic neuritis episode (MS-ON), with no prior episode (MS-NON) and control subjects. Results There were significant differences ( p < 0.05, analysis of variance) between MS-ON ( n = 25 eyes) and healthy eyes ( n = 25 eyes) for all RNFL parameters measured by OCT and GDx. Significant differences between MS-NON ( n = 75 eyes) and healthy eyes were also found for most of these parameters. RNFL thickness in the temporal quadrant was the parameter with the greatest differences between groups (71.79 μm in healthy eyes, 60.29 μm in MS-NON and 53.92 μm in MS-ON, p < 0.0005). Although there was a highly significant but moderate correlation between RNFL thickness and duration of the disease, no correlation was observed between RNFL thickness and neurologic impairment (Expanded Disability Status Scale). Conclusions Axonal loss was detected not only in MS eyes with a previous acute optic neuritis, but also in MS eyes with no known optic neuritis episode. Structural abnormalities correlate with functional assessments of the optic nerve.

Introduction Optic neuritis causes retinal nerve fiber layer damage, which can be quantified with optical coherence tomography. Optical coherence tomography may be used to track nerve fiber layer changes and to establish a time-dependent relationship between retinal nerve fiber layer thickness and visual function after optic neuritis. Methods This prospective case series included 78 patients with optic neuritis, who underwent optical coherence tomography and visual testing over a mean period of 28 months. The main outcome measures included comparing inter-eye differences in retinal nerve fiber layer thickness between clinically affected and non-affected eyes over time; establishing when RNFL thinning stabilized after optic neuritis; and correlating retinal nerve fiber layer thickness and visual function. Results The earliest significant inter-eye differences manifested 2-months after optic neuritis, in the temporal retinal nerve fiber layer. Inter-eye comparisons revealed significant retinal nerve fiber layer thinning in clinically affected eyes, which persisted for greater than 24 months. Retinal nerve fiber thinning manifested within 6 months and then stabilized from 7 to 12 months after optic neuritis. Regression analyses demonstrated a threshold of nerve fiber layer thickness (75μm), which predicted visual recovery after optic neuritis. Conclusions Retinal nerve fiber layer changes may be tracked and correlated with visual function within 12 months of an optic neuritis event.
