Optic neuritis in multiple sclerosis

A 40-year-old writer, living in London, UK, had multiple sclerosis with right optic neuritis (ON)1 confirmed by ophthalmologic and neurophysiologic evaluations. During ON, he represented what he was able to see with his right eye. Two weeks later, blurred vision, decreased visual acuity, dyschromatopsia, and lower contrasts were still evident (figure, B). IV steroids therapy was administered. At week 4, color and contrast perception gradually improved (figure, C). Six months after ON, he experienced a partial vision recovery, with the persistence of an increased contrast perception (figure, D). These pictures provide insight regarding ON-related visual changes, from a patient's perspective. Acknowledgment: The authors thank the patient for his availability.
