Septo-Optic Dysplasia

Septo-Optic dysplasia is early under development of the brain. Although characteristics of this condition can vary the areas of the brain that are effected by the under development are the optic nerve, the pituitary gland and abnormal formation of structures along the midline of the brain.

Sight can be effected through this condition due to the under development of the optic nerve. This under development means that visual signals can not be effectively transmitted to the brain. This causes the sight problem.

Another characteristic of septo-optic dysplasia is the abnormal development of structures separating the right and left halves of the brain.
While the brain is being formed during pregnancy, some structures may form abnormally or fail to develop at all. Depending on which areas of the brain are affected, abnormal brain development can lead to intellectual disability and other neurological problems.

Another feature of this disorder is pituitary hypoplasia (under development). One of the functions of the pitruitary gland (master gland is to distribute hormones into the body to control the body, such as growth, thyroid and female and male hormones. Underdevelopment of the pituitary can lead to a shortage (deficiency) of many essential hormones.

Septo-optic dysplasia has a reported incidence of 1 in 10,000 newborns.
