History A 16 year old male presented to an outside center with binocular horizontal diplopia. His symptoms began approximately six months prior when he noticed difficulty reading. He was seen by an optometrist and prescribed reading glasses. His vision was 20/66 in the right eye and 20/25 in the left eye. He had previously been diagnosed with amblyopia as a child. There was no family history of ophthalmic or neurologic issues. Over the next two months he lost the ability to adduct the right eye. At the emergency department, a brain MRI revealed a large T2 high signal area involving the dorsal midbrain. He denied any visual changes at that time but OCT revealed RNFL loss temporally. He was diagnosed with bilateral internuclear ophthalmoplegia (INO) and treated with intravenous methylprednisolone for three days followed by a course of oral steroids. Despite this treatment and a course of IVIG the following month, he continued to deteriorate. He developed upbeat and downbeat nystagmus with a >50 prism diopter exotropia in primary gaze with adduction and downgaze paresis and 70% limitation of upgaze in both. At the same time he noticed a decrease in the vision of his right eye (CF OD, 20/30 OS). He was uncertain of the tempo of onset as he had been patching his right eye due to the diplopia. There was no pain on eye movements. Neurological examination was unremarkable for other focal deficits. A diagnostic procedure was performed.
