Septo-optic dysplasia

Hypothalamic-pituitary function in children with optic nerve hypoplasia. Thank you for updating your details.

Agenesis of the septum lucidum with malformation of the optic tract]. Endocrine disorders in septo-optic dysplasia De Morsier syndrome – evaluation and follow up of 18 patients. Am J Dis Child ; The most commonly affected hypopituitary hormone is growth hormone. It is good to remember that hypothyroidism not treated in the first 3 years of life has adverse effects in the development of the brain, maybe contributing to the developmental delay observed in these cases.

The magnetic resonance imaging Displlasia findings are heterogeneous including morphological anomalies of the cortex and malrotation of the hippocampus The electroencephalogram ECG is normal in half of the cases 19, Optic nerve hypoplasia with intracranial arachnoid cyst. Septo-optic dysplasia SODalso referred to as de Morsier syndrome, is a rare congenital condition, characterized by two of the classic triad features: The diagnosis of this rare congenital anomaly is made when 2 or more features of the classic triad are present.

Gonadotrophic function is generally preserved 26 and diabetes insipidus is found more rarely 5, The retinal vessels are normal 6.

Clin Endocrinol Oxf ; Other important characteristic to be remembered on the follow-up of these patients is the evolution of the endocrine deficiencies through time, as occurred with two patients, which demands selto vigilance and periodic reevaluation of the endocrine function 7,18, HESX1 mutations are an uncommon cause of septooptic dysplasia and hypopituitarism.

Endocrine status in patients with optic nerve hypoplasia: We observed that 4 of the 5 cases have endocrine disfunction and this is probably a selection bias, since the patients were referred to our outpatient clinic due to short stature of possible endocrine causes. Studies in mice showed that the disruption of the homeobox gene Hesx1 produces a phenotype similar to SOD 4.
