-
- Septo-Optic Dysplasia is a birth defect characterized by a malformed optic
- disk, pituitary deficiencies, and often the absence of the "septum pellucidum"
- which separates the anterior horns of the lateral ventricles of the brain. As
- a consequence of these abnormalities visual impairment and/or deviation of the
- eyes, and deficiencies of pituitary hormones such as adrenocorticotropic
- hormone (ACTH), prolactin, thyrotropin releasing hormone and/or growth hormone
- may occur.
-
- Symptoms
-
- Symptoms of Septo-Optic Dysplasia are present at birth. The primary symptom
- is decreased sharpness of vision. An involuntary rapid horizontal, vertical,
- or rotatory movement of the eyeballs (nystagmus) may also occur and the
- response of the pupils to light may vary among patients. Deviation of the
- eyes inward and outward (esotropia and exotropia) sometimes also occur.
-
- The extent of pituitary hormone deficiency may vary. In a few cases
- prolonged yellow skin discoloration (jaundice) occurs at birth. Mental
- retardation or learning disabilities may also occur. If growth hormone
- deficiency is not treated during childhood, the child's growth may be stunted.
-
- Causes
-
- The cause of Septo-Optic Dysplasia is not known. There is no evidence that
- this is a hereditary disorder.
-
- Affected Population
-
- Children born with Septo-Optic Dysplasia are often first born children of
- young mothers. This very rare disorder affects males and females in equal
- numbers.
-
- Related Disorders
-
- Symptoms of the following disorder may resemble those of Septo-Optic
- Dysplasia. Comparisons may be useful for a differential diagnosis:
-
- Absent Septum Pellucidum with Porencephalies is a rare disorder
- characterized by atrophy of one part of the brain (hemiatrophy), rapid
- movements of the eye (nystagmus), seizures and short stature. These symptoms
- are present at birth.
-
- Therapies: Standard
-
- Treatment for Septo-Optic Dysplasia is symptomatic and supportive.
- Deficiencies of pituitary hormones such as ACTH may be treated by hormone
- replacement therapy such as synthetic ACTH or cortisone, and/or human growth
- hormone.
-
- Therapies: Investigational
