A child diagnosed with ONH will undergo a number of evaluations and brain function tests. The optic disc appears abnormally small, because not all the optic nerve axons have developed properly. As noted above, neuroimaging and investigation of the hypothalamic/pituitary axis are critical in identifying potentially life-threatening hormonal dysfunction. Occasionally, optic nerve hypoplasia may be compatible with near-normal vision; in other cases, one or both eyes may be functionally, or legally blind. I was born with optic nerve hypoplasia in my right eye. You will need to make sure your child is under the care of an endocrinologist, a doctor who specializes in hormone problems.

Hormonal imbalances may require hormone replacement therapy. Thyroid-stimulating hormone or TSH: This hormone controls production of thyroid hormone which, if missing, can cause poor growth, low energy, dry skin, constipation, feeling cold frequently, more weight gain than height gain, and, in some cases, delayed intellectual and physical development. 1997;104(3):493-496.

Ronald Reagan Reagan was diagnosed with myopia. In my case, my parents noticed that something was different about me when I was six months old when I began looking directly into the sun. proposed instead the syndrome of optic nerve hypoplasia.6 Although there may be an association with congenital absence of the septum pellucidum (Fig. The prognosis for each patient will be different, though, depending on what other conditions they have alongside their optic nerve hypoplasia. When a person doesn'tt make hormones correctly, this is called hypopituitarism. Southern California Clinical and Translational Science Institute (SC CTSI).

There have been a few genetic variations found in patients with ONH/Hypopituitarism. The areas that can be affected involve gross and fine motor skills; intelligence, speech and interacting with people. Because of this, all children with ONH are at risk for developmental delays and hormonal deficiencies, regardless of severity of ONH, or whether abnormalities are visible by MRI. Ophthalmology. WebAcute zonal occult outer retinopathy (AZOOR) is a retinal disease characterized by sudden onset of flashing lights and visual field changes in an individual with a normal retinal exam. Is there a cure for ONH? 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. It is often associated with endocrinopathies (hormone deficiencies), developmental delay, and brain malformations. Gallery Tilted optic disc in left eye of a 20 years old male.

I eventually graduated from high school with honors, received my Bachelors and a Masters degree in Social Work and worked full time in professional human services for five years. A child does not have to have all 3 features (meaning optic nerve hypoplasia, abnormal midline structures of the brain, and pituitary gland hypoplasia) to be diagnosed with ONH/Hypopituitarism. Clinical examination. These strategies are highly individualized, and I could devote an entirely separate blog post describing them. In those diagnosed with ONH, however, there are noticeably fewer nerves. Growth hormone: Symptoms of low growth hormone include slow growth and short stature.

Generally surgery results in improved appearance only and not in improved visual function.[3]. [2] Many transcription factors for eye development are also involved in the morphogenesis of forebrain, which may explain why ONH is commonly a part of a syndrome involving brain malformations.[2].

Other indicators of GH deficiency may include hypoglycemic events (including seizures), prolonged jaundice, micropenis in boys, and delayed dentition. [3], Dysfunction of the hypothalamus results in loss of regulation over behavior and function of the pituitary gland (master gland). Vision loss is not progressive; in fact, vision may improve slightly over time, and nystagmus may decrease. Although there are no treatments for ONH itself, the ophthalmologists early identification of this condition allows for prompt investigation of associated neuroendocrine disorders that can have a profound impact on the patients systemic health and may be amenable to timely intervention. Anti-diuretic hormone (ADH): This hormone helps the kidneys concentrate urine when a child is dehydrated. [12] The incidence of ONH is increasing, although it is difficult to estimate the true prevalence.

OCT can also demonstrate thinning of inner retinal layers when there is associated foveal hypoplasia (Fig. The hypothalamus is a part of the brain that coordinates the endocrine system, which monitors hormones, with the nervous system. It is now clear that the absence of the septum pellucidum does not correlate with the associated symptoms of ONH. There is no treatment to cure ONH/Hypopituitarism. Additionally, the individual is likely to bump into side-lying and low-lying obstacles; he or she should learn orientation and mobility (travel) techniques, such as the use of a cane, to avoid obstacles.

This condition is the most common congenital optic nerve anomaly. Magnetic resonance imaging (MRI) can demonstrate asymmetry of the caliber of the optic nerve in most moderate to severe cases (Fig. [3], Mutations of genes involved in transcription regulation, chromatin remodelling, -dystroglycan glycosylation, cytoskeleton and scaffolding protein, RNA splicing, and the MAP kinase signalling pathway are currently known to cause ONH. Children with these abnormalities can have seizures or intellectual disabilities. Stem cells research is the most promising form of therapy for ONH in the future; unfortunately, it is far from ready for use in humans.
