ICD-Code Q04.4: Septo-optic dysplasia
Parts of the brain have not formed correctly.
The brain is located inside the head. It receives, processes and stores sensory impressions. The brain controls movements and various physical functions.
The defect affects areas at the front of the brain, for example. This is where the optic nerve is situated. As a result of the defect, the optic nerve is unable to develop or can only develop partially. The defect can cause vision impairment or blindness, depending on its severity. The defect may also affect the pituitary gland.The pituitary gland is a gland in the brain. Many hormones are produced in this gland. Hormones are chemical messengers for the body. These messengers produced by the pituitary gland influence growth, metabolism and sex hormones, for example.A defect in the pituitary gland may cause a deficiency in the amount of hormones produced for the body. This can affect the metabolism, for example. The organs may be unable to work properly as a result. Seizures can also occur.
