Optic nerve hypoplasia is a failure of the optic nerve to develop fully. Optic nerve hypoplasia can be associated with central nervous system (CNS) malformations which put the patient at risk for other problems, including seizure disorder and developmental delay. The aim of this study was to investigate the clinical phenotypes of a large cohort of children with SOD, Multiple Pituitary Hormone Deficiency (MPHD) and Optic Nerve Hypoplasia (ONH), with a focus on endocrine testing. Superior segmental optic nerve hypoplasia (SSOH) is defined as a nonprogressive congenital anomaly affecting the optic nerve head and is characterized by a localized inferior visual field defect, superior retinal nerve fiber layer (RNFL) defect, and good visual acuity. 1 It is a non-progressive congenital disease characterized histologically by a subnormal number of optic nerve axons in the optic nerve tracts resulting in small, pale optic discs.

Optic nerve hypoplasia (ONH) is a nonprogressive congenital abnormality of one or both optic nerves associated with a diminished number of axons in involved nerves with normal development of supporting tissues and the retinal vascular system. The retina is the light sensitive tissue at the back of the eye. The syndrome of optic nerve hypoplasia (ONH) is the under-development or absence of the optic nerve combined with possible brain and endocrine abnormalities. The effects of optic nerve hypoplasia have a broad range dependent on the adequacy of visual messages sent from the eyes to the brain, from little or no visual impairment to near-total blindness. , McNally R.

Now at epidemic proportions, ONH is the single leading ocular cause of blindness and visual impairment in young children. Although the conventional characterization of SSOH emphasizes the relatively superior entrance of the central retinal artery, the pallor of the superior optic disc, a superior peripapillary halo, and thinning of the superior nerve. Celebrity. Normal measurements of the optic nerve, optic nerve sheath and optic chiasm in the adult population. The lesion is not necessarily associated with visual impairment. The exact pathophysiology of SSONH remains elusive, but a mechanism. Individuals with aniridia characteristically have a variable degree of iris hypoplasia and foveal hypoplasia, which leads to nystagmus and impaired visual acuity (usually 20/100 - 20/200 BCVA).
