Optic nerve hypoplasia with posterior pituitary ectopia: male predominance and nonassociation with breech delivery.

PURPOSE: To determine whether posterior pituitary ectopia in children with optic nerve hypoplasia has a male predominance or an increased incidence of breech delivery.

METHOD: Retrospective analysis of 12 children with optic nerve hypoplasia and posterior pituitary ectopia.

RESULTS

Eleven of 12 patients with posterior pituitary ectopia were boys. No child had a history of breech delivery. Two children had a history of breech positioning but were delivered by cesarean section.

CONCLUSION

Posterior pituitary ectopia with optic nerve hypoplasia shows a strong male predominance but no association with breech delivery.
