It is often unclear if the hypopituitarism is due to a primary pituitary dysfunction or is secondary to a hypothalamic dysfunction. The procedure lasted about 80 min and the patient morsierr transported to the postanesthetic care unit, conscious and in spontaneous ventilation.

Endocrine status in patients with optic nerve hypoplasia: According to Rush and Bajandasthe term ‘septooptic dysplasia’ was coined in by de Morsier, who pointed out the association of optic nerve hypoplasia and absence of the septum pellucidum. While the OMIM database is open to the public, users seeking information about a personal medical or genetic condition are urged to consult with a qualified physician for diagnosis and for answers to personal questions.

Prediction of intellectual outcome in infancy is difficult. De Morsier 2inassociated optic nerve hypoplasia to septum pellucidum agenesis and coined the term “septo-optic dysplasia” SODlater to be recognized as De Morsier syndrome.

Prognosis Prognosis is variable, depending on the severity of the disease. Novel HESX1 mutations associated with a life-threatening neonatal phenotype, pituitary aplasia, but normally located posterior pituitary and no optic nerve abnormalities. This study showed that even though most sporadic cases cannot be attributed to HESX1 gene mutations, a pattern of heterozygous autosomal dominant inheritance with incomplete penetration exists. The mortality related to general anesthesia in such patients put us some challenges.
