- Retinal Nerve Fiber Layer Thickness at Baseline and Month 6 [ Time Frame: Baseline and Month 6 ]Axonal loss in the optic nerve (due to optic neuritis) was assessed by measuring retinal nerve fiber thickness of the affected eye using optical coherence tomography (OCT) at Baseline and Month 6.
- To Evaluate Changes on Additional OCT Parameters and Other Visual Function and Clinical Parameters. [ Time Frame: 6 months ]
