However, the IV methylpredisolone group reported the perception of better vision on a patient questionnaire than the other two groups and had improved contrast sensitivity, visual field, and color vision at 6 months follow-up. Lymphocytes cross the blood-brain barrier, resulting in axonal loss by destruction of the myelin sheath 2.
