What is the recommended initial treatment approach for optic neuritis?

• A. Refer for imaging and start oral steroids if within 1-2 weeks of onset
• B. Immediate IV steroids without imaging
• C. Observation only
• D. Start antibiotics for possible infection

Answer: (A)

The main idea here is that optic neuritis should be evaluated and treated promptly to both confirm the diagnosis and speed recovery. The initial step is to obtain imaging to confirm optic neuritis and to look for signs of demyelinating disease (usually an MRI of the brain and orbits with contrast). Once imaging is in progress or completed, starting corticosteroid treatment within a couple of weeks of onset can speed visual recovery. Oral high‑dose steroids are an option in this early window and have been shown to help reduce inflammation and hasten improvement, whereas delaying treatment often means a slower return of vision. The other options aren’t appropriate: treating with antibiotics isn’t indicated for a straightforward inflammatory optic neuropathy, observation alone misses an opportunity to improve recovery, and giving steroids without at least some imaging assessment risks missing other causes or comorbidities.
