Septo-optic dysplasia is a congenital condition (present at birth). Superior segmental optic nerve hypoplasia (SSOH), or topless disc syndrome, is a congenital eye condition where a part of the optic nerve is underdeveloped. Superior segmental optic hypoplasia (SSOH) is a non-progressive congenital optic nerve anomaly characterized by a relative superior entrance of the central retinal artery, pallor of the superior optic disc, superior peripapillary scleral halo, and thinning of the superior retinal nerve fiber layer (RNFL) []. These stem cells are delivered by injection into the peripheral blood. narrated by william shatner. " Nolan has spoken about his visual impairment caused by ONH, which he has had since birth.

It may be inherited in Miniature Poodles. Optic nerve hypoplasia is a congenital condition in which the optic nerve does not develop fully, thus giving the classic small and pale appearance of the optic nerve. g. Its association with hypopituitarism and absent septum pellucidum has been recognized for more than 40 years as “septo-optic dysplasia” or “de Morsier syndrome. In the United States, ONH is a leading cause of legal blindness in children age. The diagnosis of septo-optic dysplasia (SOD) is a clinical one and can be made when two or more features of the classical triad of (i) optic nerve hypoplasia, (ii) pituitary hormone abnormalities. Septo-optic dysplasia (SOD), previously known as de Morsier syndrome, is a rare disorder of development that involves the septum pellucidum—the thin membrane located between the two halves of the brain—as well as the eyes and the pituitary gland.

Optic nerve hypoplasia is a rare neurological disease in which one or both optic nerves are underdeveloped, preventing the animal from seeing normally. Although most cases of ONH occur as isolated cases within their respective families, the advancement in molecular diagnostic technology has made us realise that a substantial fraction of cases has identifiable genetic causes, typically de novo mutations. Optic nerve hypoplasia is a failure of the optic nerve to develop fully. Optic nerve hypoplasia is a congenital disorder characterized by underdevelopment (hypoplasia) of the optic nerves; thus, there is a decreased number of optic nerve axons. 03-) Retinitis pigmentosa (H35.
