Acute optic neuritis and the prognosis for multiple sclerosis
Journal of Neurology, Neurosurgery, and Psychiatry
|March 1, 1976
Summary
Acute optic neuritis in adults shows seasonal variation. Within 15 years, 78% of patients develop multiple sclerosis, though many maintain an active life.
Area of Science:
- Neuroscience
- Ophthalmology
Background:
- Acute optic neuritis is an inflammatory condition affecting the optic nerve.
- It is often associated with an increased risk of developing multiple sclerosis.
Purpose of the Study:
- To investigate the long-term outcomes and prognosis of adult patients experiencing acute optic neuritis.
- To determine the incidence and seasonal variation of acute optic neuritis.
Main Methods:
- Retrospective analysis of 144 adult cases of acute optic neuritis.
- Life-table analysis to estimate the cumulative probability of developing multiple sclerosis.
- Patient review to assess functional status and independence.
Main Results:
- A statistically significant seasonal variation in the incidence of optic neuritis was observed.
- The probability of developing multiple sclerosis 15 years after an optic neuritis episode was 78%.
- Of patients with multiple sclerosis, 73% were independent and leading active lives at follow-up.
Conclusions:
- Acute optic neuritis in adults has a significant association with the development of multiple sclerosis.
- Despite the high risk of multiple sclerosis, many patients can maintain a good quality of life.
