Pediatric internuclear ophthalmoplegia.

BACKGROUND: Internuclear ophthalmoplegia (INO) is a rare eye movement disorder in the pediatric population. METHODS: We performed a retrospective review at a university-based tertiary referral ophthalmology practice from 2004 to 2012 to identify pediatric patients with INO. RESULTS: Three patients with INO were identified. Etiologies included high-grade astrocytoma, perinantal hypoxia and neonatal intracerebral hemorrhage. One of our patients, a 2 year-old girl, is the youngest reported case of INO. CONCLUSION: While rare, INO in a pediatric patient requires a full neurologic evaluation and careful follow-up to assess eye position and potentially treat amblyopia.
