A 30-year-old presents with sudden visual loss and pain on motility. Why?
Analysis
In this visual field, there is evidence of a defect in the left eye (left image). Both the total deviation and the pattern deviation show abnormalities. Specifically, the pattern deviation shows a central scotoma. The right eye (right image) is within normal limits. The OCT of the nerve showed some non-specific changes (video).
The patient was diagnosed with retrobulbar optic neuritis.

Neuro Coach Tip
In a patient with or without a visual field defect who presents with visual loss and pain with motility, retrobulbar optic neuritis needs to be considered.
