Optic Neuritis Clinical Trial
Official title:
The Effect of Fampridine-SR on Visual Function in Poorly Recovered Optic Neuritis in Persons With MS
Optic Neuritis (ON) is a condition that occurs in approximately 50% of individuals with relapse remitting MS, and is the presenting event in 15-20% of patients who go on to develop MS. These ON events present with a decline in vision over several days with painful eye movements. The purpose of this study is to collect pilot data on the effect of Fampridine-SR on the recovery of visual function after demyelinating optic neuritis.Our team evaluated a person with ON who had incomplete recovery which was quite bothersome to her. After a one-month treatment course Fampridine SR,her visual functioning improved. Based on this case, we present a unique opportunity to evaluate the potential benefit of Fampridine-SR as a potential treatment for persons who do not fully recover from acute ON.
Optic Neuritis (ON) is a condition that occurs in approximately 50% of individuals with relapse remitting MS, and is the presenting event in 15-20% of patients who go on to develop MS. ON usually presents with a decline in vision over several days to weeks with painful eye movements. Fampridine-SR is currently a Health Canada approved medication to treat walking impairment in persons with MS. Some small studies in the past have shown that Fampridine-SR may also have positive effects on visual functioning in those experiencing ON. This study will aim to assess the effect of taking Fampridine-SR for 8 weeks in 20 MS patients with unresolved optic neuritis on measures of visual functioning, and to determine the best measures to use in a future large scale study. The results of this study will also be used to estimate how many participants we will need in the future large scale study. ;
