case_images: Disc photographs, Goldmann visual fields, and MR images of patient 1. (a)-(f) represent the initial episode in the right eye and (g)-(l) represent the recurrence in the left eye. Figure (e) is a coronal STIR image showing high signal within the right optic nerve, and Figure (f) is a coronal T1 fat saturation postgadolinium image showing associated optic nerve enhancement. (k) and (l) are coronal STIR and T1 postgadolinium images showing left optic nerve swelling and enhancement.

case_images: Magnetic resonance (MR) imaging performed 2 weeks after the onset of her symptoms showed hyperintensity on STIR images and Gadolinium enhancement of the intraorbital portion of the right optic nerve (Figures 1(e) and 1(f)). MR imaging showed STIR hyperintensity and enhancement of the left optic nerve (Figures 1(k) and 1(l)).

case_images: Goldmann visual fields performed on patient 2 at presentation of a recurrent episode of left retroorbital pain (a) and 2 months following treatment with intravenous methylprednisolone (c). The right eye had sustained an episode of optic neuritis previously (b and d).

case_images: Visual acuity remained 6/5, and Goldmann perimetry was normal (Figure 2(a)). Her left visual function and visual field had remained unchanged on follow-up 2 months after treatment with intravenous methylprednisolone (Figure 2(c)).

case_images: Goldmann visual fields showing minimal change in the left eye 1 month after a recurrent episode of optic nerve swelling (c) compared with visual fields performed 4 months before this recurrence (a). The contemporaneous right visual fields (b and d) are presented for comparison.
