I would appreciate any info on this condition.
What part of the eye is the optic disc?
What is hypoplasia?
How does this occur? Congenital?
Associated with gene abnormalities?
Treatment? Amelioration?

Optic nerve hypoplasia is a congenital condition in which the optic nerve fails to develop completely. (The optic disk is the head of the optic nerve.) Optic nerve hypoplasia means that the nerve is physically smaller than it should be. The condition has varying degrees of severity. When the abnormality is mild, normal vision is possible. With more severe involvement, vision can be severely impaired.
Approximately one third of individuals with optic nerve hypoplasia have associated brain deficiencies.
Septo-optic dysplasia is a condition in which optic nerve hypoplasia is associated with other brain abnormalities. This condition is sometimes called de Mosier's syndrome. In this condition, the optic nerve abnormality is associated with short stature due to growth hormone deficiency, eye movement disorders, and diabetes insipidus.
Although optic nerve hypoplasia cannot be treated, de Mosier's syndrome can be treated to prevent associated illnesses.
