A condition called nystagmus, or uncontrollable shaking of the eyes, commonly accompanies optic nerve hypoplasia, as does a misalignment of the eyes called strabismus. The research studies conducted on all aspects of ONH have led to the information and scientific publications, featured here. E-mail: However, recent research indicates that children with Septo Optic Dysplasia show the same medical, developmental and psychosocial characteristics as other children with ONH and an intact Septum Pellucidum. The appearance of ONH should be distinguished from the following conditions: In addition, severe bilateral cases of ONH may mimic achromatopsia or Leber congenital amaurosis. Generally surgery results in improved appearance only and not in improved visual function.[3]. An individual with poor visual acuity may have difficulty recognizing faces and facial expressions as well as accessing near and detailed information.

Nevertheless, congenital midline brain disorders such as hypoplasia or agenesis of the corpus callosum and pituitary malformations are commonly associated with ONH, as are hydrocephalus and arachnoid cysts.5 Hypothalamic dysfunction is the most commonly seen clinical comorbidity. Even with close and careful monitoring, the endocrine deficiencies can be dangerous to those afflicted. The optic chiasm is the place within the brain where some of the nerves from each eye cross. The absence of the septum pellucidum does not predict developmental delay. Besides having small optic nerves, persons with ONH can have agenesis of the corpus callosum, absence of the septum pellucidum, maldevelopment of the anterior and posterior pituitary gland, and anomalies of the hypothalamus.

The objectives of this research registry are to determine the clinical prenatal risk factors of ONH and to investigate the clinical characteristics associated with functional outcomes in order to identify opportunities for therapeutic and rehabilitative interventions. Hypopituitarism is present in 75% to 80% of patients with ONH. This condition is the most common congenital optic nerve anomaly. Abnormal development of the corpus callosum may or may not cause abnormal brain functions, and the effects can range from mild to severe. Otherwise, children with ONH are expected to lead full, active lives.

Septo-optic dysplasia: MedlinePlus Genetics 2013;15(1):78-89. However, in situations in which the optic nerve hypoplasia also accompanies neurodevelopmental abnormalities, young children may experience developmental delays and behavioral difficulties. Oxytocin is also produced in the posterior pituitary gland. Abnormalities evident via neuroradiography can include agenesis (absence) or hypoplasia of the corpus callosum, absence or incomplete development of the septum pellucidum, malformations of the pituitary gland, schizencephaly, cortical heterotopia, white matter hypoplasia, pachygyria, and holoprosencephaly.
