Optic Neuritis During Lactation: A Case Series.

Abstract

Optic neuritis is a rare condition that can lead to sudden blindness and also could be a precursor to multiple sclerosis. When it occurs postpartum during lactation, it is called lactation optic neuritis. We present four cases of optic neuritis in lactating mothers, two of which had additional features of demyelinating disease upon neurological imaging. All participants were treated with high dose intravenous steroids followed by 11 days of oral steroids, per the optic neuritis treatment trial, which led to complete recovery of vision. Two participants with demyelinating disease on magnetic resonance imaging scans were advised to wean, because of a need for immunosuppressive therapy later. Optic neuritis during lactation should be suspected following acute loss of vision. Prompt referral to an ophthalmologist is mandated for early diagnosis and treatment to prevent long-term co-morbidities.
