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

Optic nerve hypoplasia symptoms. The detection of optic nerve hypoplasia may vary based on the child. The first signs parents may notice in infants may include: Rapid, involuntary eye movements (nystagmus) Signs of vision impairment in one or both eyes. Delays in development of some motor skills.

Optic nerve hypoplasia is a condition in which the optic nerve is underdeveloped. This often results in a small optic nerve. This is due to a problem with the development of the eyes in utero.

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 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

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.

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.

Optic nerve hypoplasia (ONH) is an important cause of congenital visual impairment in children and infants. It is a unilateral or bilateral malformation of the optic nerve with a wide spectrum of severity.

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

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 medical condition where the optic nerve, the nerve that carries messages from the eyes to the brain, is underdeveloped before or during birth. It is one of the most common causes of visual impairment in children less than 3 years old. Individuals with Optic Nerve Hypoplasia may also have hypopituitarism

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

Optic Nerve Hypoplasia. Optic Nerve Hypoplasia refers to the underdevelopment of the optic nerve during pregnancy. The dying back of optic nerve fibers as the child develops in utero is a natural process, and ONH may be an exaggeration of that process. ONH may occur infrequently in one eye (unilateral) but more commonly in both eyes (bilateral).

Optic Nerve Hypoplasia (ONH) is an ocular condition that occurs when the optic nerve does not fully develop. This usually occurs in the first trimester of pregnancy for unknown reasons. It can be unilateral (in one eye) or bilateral (in both eyes). Once considered a rare disorder, ONH is fast becoming a leading cause of childhood blindness in

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
