Presentation
Each diagnosis includes clinical presentation(s) of affected patients, the best sequences for imaging analysis, expected imaging sequences (in both common and uncommon presentations), and imaging examples of key features. [books.google.com]
The spectrum of its clinical presentation is broad. Most bilateral cases will present with ophthalmic abnormalities such as poor vision and wobbly eyes (nystagmus). Unilateral cases present with strabismus because the affected eye tends to drift. [eye.com.ph]
Each patient presented with congenital nystagmus and was diagnosed with isolated absence of the optic chiasm on the basis of neuroimaging. [ajnr.org]

Workup
Endocrine workups include: fasting morning cortisol and glucose, TSH, free4, growth hormone surrogates (IGF-1, IGFBP-3), LH, SFH, and testosterone (if < 6mo age). [eyewiki.aao.org]
Treatment
No treatments have been shown to improve vision in these children. [elsevier.com]
Those with normal growth but determined to be GH-deficient by a glucagon stimulation test will be randomized to treatment with GH vs control (no intervention; observation only). [clinicaltrials.gov]
Is there any treatment for optic nerve hypoplasia? There is no medical or surgical treatment for ONH. However, occlusion of the better seeing eye may improve vision in the other eye. [aapos.org]
Treatment Treatment Options: There is no treatment for the optic nerve hypoplasia but individuals need to be monitored for endocrinopathy and treated appropriately. Low vision aids and sometimes mobility training can be helpful for some patients. [disorders.eyes.arizona.edu]
However, there is no specific treatment for the optic nerve anomaly. [eye.com.ph]
Prognosis
What is the visual prognosis associated with it? The visual potential is determined by the integrity of the central retinal axons and does not necessarily correlate with the size of the optic disc. [eye.com.ph]

Etiology
Etiology and Pathophysiology Genetic etiologies usually involve defects in mitochondrial function. Exposure of retinal nerve cells to light normally results in the generation of free radical species. [unboundmedicine.com]
Palabras clave: neurohipófisis ectópica, hipoplasia del nervio óptico, resonancia magnética Hypoplasia of the optic nerve is a rare congenital anomaly of unknown etiology that is a frequent cause of blindness in children. [elsevier.es]
The exact etiology is unknown, with an underlying genetic defect currently accounting for 9. All imaging modalities that can visualize the septum pellucidum (ultrasound, CT and MRI) will detect its absence in septo-optic dysplasia. [radiopaedia.org]
This represents a first step towards defining the ONH etiology and developing ONH prevention and treatments strategies. [grantome.com]

Pathophysiology
Additional information is included concerning the pathophysiology and pathology of the disorders being discussed as well as basic information concerning the causative genes (when appropriate). [books.google.com]
The pathophysiologic basis for decussation of retinal axons is an area of active research. Pathfinding of retinal axons at the optic chiasm is incompletely understood at this time. [ajnr.org]
Etiology and Pathophysiology Genetic etiologies usually involve defects in mitochondrial function. Exposure of retinal nerve cells to light normally results in the generation of free radical species. [unboundmedicine.com]
This suggests that either there is some other pathophysiological process underlying the reduced structural integrity of their optic radiations, or that even small reductions in visual stimulation can affect the development of the optic radiations. [journals.plos.org]
Prevention
This represents a first step towards defining the ONH etiology and developing ONH prevention and treatments strategies. [grantome.com]
Yet there is no treatment to prevent or repair malformation of the optic nerve. Mukherjee and his colleague Michael Fox, an associate professor at the Virginia Tech Carilion Research Institute, want to change that. [augustafreepress.com]
