SOD is a condition that can involve multiple problems in the midline structures of the brain, stemming from miswiring of the brain and central nervous system. Many times, de Morsiers Syndrome or septo-optic dysplasia (SOD) is associated with ONH, however, it is possible to have ONH without any additional issues like SOD. Other proposed gene associations include OTX2 and PROKR2.5. In affected individuals, Additionally, this research registry functions as an umbrella study for the development of more specialized investigations of the syndrome. However, the correlation seems to be small, as the majority of those with optic nerve hyposplasia do not have these gene mutations. Patients with ONH exhibit an optic nerve that appears smaller than normal and different in appearance from small optic nerves caused by other eye conditions such as optic (nerve) atrophy.[3]. The vision of a child with ONH/Hypopituitarism can be quite variable ranging from normal to almost blind, or anywhere in between.

However, if your child has a more severe visual impairment in one eye, the ophthalmologist may recommend patching (occluding) the better eye in order to encourage the weaker eyes use. Her research interest is investigating the prenatal correlates of ONH, and identifying early clinical risk factors for adverse developmental outcomes in children with ONH. The absence of the septum pellucidum does not predict developmental delay. Estimates of cerebral malformations vary from 39% to 90% of children with ONH. The testimony of previous recipients that stem cell therapy resulted in improved vision bears little scientific merit as many children with ONH enjoy late, spontaneous improvement in vision.
