What is the prognosis for vision with optic neuritis?

• A. Vision is often fully restored without treatment
• B. Vision typically recovers completely within a few days
• C. Vision is permanently poor in most cases
• D. Variable, may be guarded to poor

Answer: (D)

Prognosis for vision in optic neuritis is variable. Many people recover substantial or even near-normal vision over weeks to months, and high-dose steroids can speed that recovery, but the final outcome isn’t guaranteed and can range from good to partial or persistent impairment. Factors such as initial severity, age, and especially association with multiple sclerosis influence long-term outlook, with some individuals experiencing relapses or residual deficits. So the most accurate choice reflects this wide range: outcomes can be guarded to poor in some cases, while others improve fully.
