Baseline Magnetic Resonance Imaging of the Optic Nerve Provides Limited Predictive Information on Short-Term Recovery after Acute Optic Neuritis
Figure 2
Patients with Gd enhancement of the optic nerve show significant higher visual improvement.
(A) Mean improvement of visual acuity of patients with or without either T2 lesion or Gd enhancement of the optic nerve in orbital MRI. Error bars indicate standard error of the mean. * indicates significant difference with p = 0.04 as determined via Mann-Whitney rank sum test. Improvement of visual acuity was defined as difference between visual acuity before and after adequate treatment. (B) Mean visual acuity of patients with or without T2 lesion or Gd enhancement of the optic nerve in orbital MRI before and after adequate therapy. Error bars indicate standard error of the mean. No significant differences were found between the single groups.
