The vision of a child with ONH/Hypopituitarism can be quite variable ranging from normal to almost blind, or anywhere in between. In some instances, ONH includes the absence or abnormal development of the corpus callosum (a thick band of nerve fibers that connect the two hemispheres of the brain) and septum pellucidum (a thin membrane of connective tissue between the brains lateral ventricles). proposed instead the syndrome of optic nerve hypoplasia.6 Although there may be an association with congenital absence of the septum pellucidum (Fig. Optic Nerve Hypoplasia | Information & support | Contact Optic Nerve Hypoplasia Testing for GH may involve blood tests (IGF-1 and IGFBP-3), growth hormone stimulation test, or bone age x-ray of the hand or wrist (or body for children younger than 2 years). They may show sensory defensiveness and delays in learning fine and gross motor skills, which can make reading braille and learning basic daily living skills, like dressing, grooming and personal hygiene, difficult or impossible without additional supports.

However, in situations in which the optic nerve hypoplasia also accompanies neurodevelopmental abnormalities, young children may experience developmental delays and behavioral difficulties. [7], ONH is diagnosed by ophthalmoscopic examination. Dr. Garcia-Filions expertise is in database infrastructure and the application of research and statistical methodology to advance research objectives.
