Methods Contrast sensitivity was tested on 34 eyes of 34 amblyopic patients who had been successfully treated (visual acuity ≥5.0). Forty normal subjects (40 eyes) were used as age-matched controls.

Sensory impairment and urinary dysfunction also had developed, and paraparesis persisted after the hypokalemia was corrected during hospitalization. An optokinetic nystagmus test showed bilateral sick waves and at the same time a cerebrospinal fluid analysis was normal. A blood examination disclosed borderline anti-nuclear antibodies and an elevated serum IgG level. Her cervical spinal cord showed mild swelling and contrast-enhancement when examined by magnetic resonance imaging. Neither a brain stem nor an optic nerve's lesion was found. Based on the above, acute transverse myelitis was diagnosed. All the symptoms present in the patient relieved gradually after 5-days of pulsed intravenous methylprednisolone therapy.
