title: Septo-optic dysplasia (de Morsier syndrome).
abstract: A 12-year-old girl and a 30-year-old woman had bilateral optic disk hypoplasia and bitemporal hemianopia. By using computed axial tomography on our patients, we demonstrated the absence of the septum pellucidum, which confirmed the diagnosis of septo-optic dysplasia, or the de Morsier syndrome.
