Optic nerve hypoplasia (ONH) is a present-at-birth (congenital) condition where your optic nerve is small or underdeveloped. Optic nerves help you see by sending messages between your eyes and your brain. ONH can lead to vision problems like vision loss and irregular eye movements. In addition to an underdeveloped optic nerve, this condition

The effects of optic nerve hypoplasia have a broad range dependent on the adequacy of visual messages sent from the eyes to the brain, from little or no visual impairment to near-total blindness. The condition may affect one or both eyes. Infants and children with ONH may have accompanying hormone deficiencies, brain abnormalities, and

A person with Optic Nerve Hypoplasia (ONH)has small eye nerves (optic nerves) from the eye to the brain. Some people with ONH also have an abnormal brain and a poorly functioning pituitary gland. This brochure explains the problems that can occur in children with ONH. Your child may have none, any or all of these problems in a mild or more

Optic nerve hypoplasia (ONH) is a congenital disorder characterized by underdevelopment (hypoplasia) of the optic nerves. The optic nerves transmit impulses from the nerve-rich membranes lining the retina of the eye to the brain. Most people with ONH have abnormal eye movements (nystagmus) and vision can range from no light perception to good

The syndrome of optic nerve hypoplasia (ONH) is the under-development or absence of the optic nerve combined with possible brain and endocrine abnormalities. It is also known as septo-optic dysplasia or DeMorsier's syndrome. Now at epidemic proportions, ONH is the single leading ocular cause of blindness and visual impairment in young children.

Optic nerve hypoplasia (underdevelopment): The optic nerves run from the back of the eye to the back of the brain where the images that we see are processed. An ophthalmologist or eye doctor is specially trained to look at the optic nerve and tell whether it is normal in size or small. Children can often present with nystagmus which is an

https://en.wikipedia.org/wiki/Optic_nerve_hypoplasia
Optic nerve hypoplasia (ONH) is a medical condition arising from the underdevelopment of the optic nerve(s). This condition is the most common congenital optic nerve anomaly. The optic disc appears abnormally small, because not all the optic nerve axons have developed properly. It is often associated with endocrinopathies (hormone deficiencies), developmental delay, and brain malformations.

The diagnosis of ONH is typically made by the appearance of small/pale optic nerve during a dilated eye exam. There can be a surrounding halo of yellow tissue bordered by a ring which is known as the double-ring sign. The retinal vessels may appear tortuous or have fewer branches, and special imaging of the retina (optical coherence tomography

Optic nerve hypoplasia (ONH) is a congenital condition (present at birth) in which there is underdevelopment of the optic nerve. ONH can be unilateral (affecting one eye) or bilateral (affecting both eyes) and occurs in both males and females. ONH is thought to be one of the three most common causes of visual impairment in children.

Optic nerve pits rarely affect visual acuity, unless the patient develops a serous macular detachment. 5 The origin of the serous fluid is not completely understood, however. 6 The most widely accepted theories are liquefied vitreous material gaining access to the subretinal space via the optic pit, or cerebrospinal fluid from the optic nerve leaking through the optic pit into the subretinal

Abstract. Optic nerve hypoplasia (ONH) is a congenital anomaly of the optic disc that might result in moderate to severe vision loss in children. With a vast number of cases now being reported, the rarity of ONH is obviously now refuted. The major aspects of ophthalmic evaluation of an infant with possible ONH are visual assessment, fundus

Answer: Optic nerve hypoplasia may occur in one or both eyes. It sounds as if your son has only one eye involved which is fortunate. A child with poor vision could have ADHD or could have visual problems that might appear to be ADHD or behavior problems because it is hard to pay attention in school. Make sure that the myopia is well corrected

Optic nerve hypoplasia (ONH) has developed into a leading cause of congenital blindness. The frequently associated features of hypopituitarism and absent septum pellucidum were felt to have embryonic linkage as "septo-optic dysplasia" or "de Morsier's syndrome.". More recent studies have suggested these associations are independent of

Optic nerve hypoplasia (ONH) is a common complex congenital disorder of unknown cause, involving a spectrum of anatomic malformations and clinical manifestations ranging from isolated hypoplasia of 1 or both optic nerves, with a variable degree of visual impairment, to extensive brain malformations, hypothalamic-pituitary dysfunction, neurocognitive disability, and/or autism spectrum disorders

Optic nerve hypoplasia (ONH) is the most common congenital optic nerve anomaly and a leading cause of blindness in the USA. Although most cases of ONH occur as isolated cases within their respective families, the advancement in molecular diagnostic technology has made us realise that a substantial fraction of cases has identifiable genetic causes, typically de novo mutations.
