Purpose To evaluate retinal nerve fiber layer thickness (RNFLT) using optical coherence tomography (OCT) in children with acquired demyelinating diseases. Methods This is a cross-sectional study of patients seen between 2006–2008 at the Pediatric MS Center of the Jacobs Neurological Institute. Consensus definitions for pediatric demyelinating disease were followed. All children received OCT testing and assessment of visual acuity (VA) using Snellen and low contrast letter acuity (LCLA) charts. Results Thirty-eight children diagnosed with acquired demyelinating disease, 15 healthy controls, and five children with other neurological disorders (OND) were included. Average RNFLT in healthy controls was 107 ± 12 μm( n = 30) versus 108 ± 5 μm ( n = 10) in OND controls. In children with multiple sclerosis, average RNFLT ± SD was 99 ± 14 μm in unaffected ( n = 24) versus 83 ± 12 μmin eyes affected by optic neuritis (“affected eyes”) ( n = 10). Average RNFLT in children with acute disseminated encephalomyelitis and transverse myelitis was 102 ± 15 μm in unaffected ( n = 18) versus 67 ± 17 μm in affected eyes ( n = 6). In children with optic neuritis (ON), average RNFLT ± SD was 97 ± 13 μm in unaffected ( n = 5) versus 89 ± 12 μm in affected eyes ( n = 9). Differences between children with demyelinating disease and controls and between ON and nonON eyes were statistically significant ( P < 0.001). Bivariate correlations of RNFLT with LCLA ( P = 0.002) and VA ( P < 0.001) were significant. Conclusions OCT may be a valuable tool for the assessment and monitoring of anterior optic pathway dysfunction in children with demyelinating diseases.

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.

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.

Background Lipoic acid, an antioxidant, has beneficial effects in experimental acute optic neuritis and autoimmune encephalomyelitis. Optical coherence tomography can detect retinal nerve fiber layer thinning, representing axonal degeneration, approximately 3–6 months after acute optic neuritis. Objective To determine whether lipoic acid is neuroprotective in acute optic neuritis. Methods A single-center, double-blind, randomized, placebo controlled, 24-week trial. Intervention included 6 weeks of once daily lipoic acid (1200 mg) or placebo within 14 days of acute optic neuritis diagnosis. The primary outcome was the mean difference in affected eye retinal nerve fiber layer (RNFL) thickness from baseline to 24 weeks. Results We enrolled 31 subjects (placebo n=16; lipoic acid n=15; average age 38.6 years (standard deviation (SD) 10.3)). Affected eye mean global RNFL thickness (µm) in the lipoic acid group decreased from 108.47 (SD 26.11) at baseline to 79.31 (SD 19.26) at 24 weeks. The affected eye RNFL in the placebo group decreased from 103.67 (SD 18.04) at baseline to 84.43 (SD 20.94) at 24 weeks. Unaffected eye RNFL thickness did not significantly change in either group over 24 weeks. Conclusion Six weeks of oral lipoic acid supplementation after acute optic neuritis is safe and well tolerated; however, because of insufficient recruitment, we could not conclude that lipoic acid treatment was neuroprotective in acute optic neuritis.

Optic neuritis (ON) is a common manifestation of multiple sclerosis (MS). Aiming to evaluate the retinal nerve fiber layer (RNFL) with optical coherence tomography (OCT), patients with relapsing-remitting (RR) MS experiencing ON were consecutively enrolled. RNFL, ganglion cell layer (GCL), foveal thickness, and macular volume were evaluated in both the ON and unaffected (nON) eye within six days from the relapse onset (T0) and after six months (T1). Ninety patients were enrolled. At T0, ON eyes showed a significantly increased RNFL when compared to the nON eyes (129.1 ± 19.5 vs. 100.5 ± 10.1, p < 0.001). At T1 versus T0, the ON eyes showed a thinner RNFL (129.1 ± 19.5 vs. 91.6 ± 20.2, p < 0.001) and a significantly decreased GCL (80.4 ± 8.8 vs. 73.8 ± 11.6; p < 0.005). No differences were found in the nON group in retinal parameters between T0 and T1. A multivariate logistic regression analysis showed that a higher number of relapses (not ON) and a greater swelling of RNFL at T0 were associated with poor recovery. The assessment of RNFL through OCT during and after ON could be used to predict persistent visual disability.
