People who suffer from Optic nerve hypoplasia tend to experience difficulty in depth perception, light, and acuity of vision. This type of eye disorder is caused by underdeveloped fibers in the optic nerve. Unlike other disorders, ONH is not genetic. Babies tend to suffer from the disease because of the pregnant mother’s lifestyle or illness. Pregnant women should avoid smoking and drinking alcohol because the chemicals could affect the health of the baby. Moreover, diabetes and other ailments in pregnant others are among the leading causes of this eye disorder in babies.
Characteristics Of Children With Optic Nerve Hypoplasia
Children with optic nerve hypoplasia tend to miss several details when they look at a particular object, person, or location. The blurry vision is worse, as compared to when a child with poor eyesight removes the eyeglasses. Some patients with ONH are not capable of detecting people or things in the peripheral field. They may also find certain difficulty in locating objects because of their problem in perceiving depth and distance.
Photophobia, or discomfort with light, is another characteristic of people with optic nerve hypoplasia. A person that suffers from this condition may avoid light by squinting or turning away from the light source. Some children who avoid outdoor activities are sometime assumed to have ONH.
Aside from visual problems, those who have ONH may also demonstrate behavioral issues. For instance, children who suffer from ONH may have a poor appetite. They are difficult to feed because of hormonal imbalance. The child may have limited choices of food, and this may be caused of absence of taste in smell among those with the ailment. A child that suffers from optic nerve hypoplasia tend to have mannerisms such as smacking the lips frequently while he or she eats.
Behavioral issues among children with ONH are due to low levels of sugar in the blood. This condition can also cause irritability and poor attention span. When the central nervous system is affected by the disorder, the child may have difficult in dealing with emotions. The child may become prone to anger, frustration, and impulsion.
Conditions Related To Optic Nerve Hypoplasia
Children that experience ONH may also have abnormalities in their brain and hormones. For instance, patients may have cerebral atrophy, insufficient hormones in the thyroid, pituitary, adrenal, and other glands.
When a person has ONH, he or she should undergo tests that would confirm the disorder. Certain complications in the brain may be detected through CT scan or MRI. On the other hand, abnormalities in hormone may be detected when the patient undergoes examination of the hormones. Those who have insufficient hormone levels are most likely to experience hormonal imbalance and other types of ailments. Low blood sugar and growth retardation can be among the causes of optic nerve hypoplasia.
