Individuals typically present with bilateral and slow vision loss starting in the first or second decade of life. [eyewiki.aao.org]

BACKGROUND OF THE PRESENT INVENTION Optic neuropathy or, often called, optic atrophy describes the loss of some or most of the fibers of the optic nerve. [google.sr]

However, pendular and triangular waveforms may also be present. The nystagmus may rarely be vertical. [diseaseinfosearch.org]

The work presented in this thesis provides further insight into the molecular and genetic basis of two classical forms of inherited optic neuropathy, namely autosomal dominant optic atrophy (DOA) and Wolfram syndrome. [ethos.bl.uk]

Besides the common symptoms described above for Leigh syndrome, retinitis pigmentosa is often present and an important diagnostic clue. [rarediseasesnetwork.org]

• Pallor

  Temporal pallor is seen in about half of patients, and the other half have total disc pallor. Pallor of the neuroretinal rim is seen universally, in contrast to glaucoma where pallor of the rim is not usually seen until late stages. [healio.com]

  Associated with this are malnutrition, failure to gain weight, frequent chest infections, and exhaustion. In the presence of a complete cleft, the tongue may cause respiratory problems by going through the cleft and into the nose. [emedicine.medscape.com]

• Malaise

  Clinical features may be non-specific and include lethargy and malaise, or reflect target organ damage and present with abnormal liver tests, cirrhosis, diabetes mellitus, arthropathy, cardiomyopathy, skin pigmentation and gonadal failure. [aetna.com]

• Plethora

  Both the retinal veins and the arteries are dilated, creating the impression of a plethora of vascular trunks on the disc. In the peripapillary zone, moderate vascular tortuosity is present. [atlasophthalmology.net]

  Humphrey visual field test shows cecocentral scotoma in right eye and central scotoma in left eye. [eyewiki.aao.org]

  Visual field testing reveals a central scotoma, a cecocentral scotoma or an enlarged blind spot. There may be extension of the scotoma to the superior temporal field in late stages. OCT shows thinning of the nerve fiber layer. [healio.com]

• Visual Impairment

  The visual impairment is usually moderate, but ranges from severe (legal blindness with acuity OPA1, which encodes a mitochondrial inner membrane protein. Optic atrophy can also be syndromic. [blueprintgenetics.com]

  Persons with OPA1 have scotomas (areas of impaired visual acuity) in the central visual fields and sparing of the peripheral visual fields. [ncbi.nlm.nih.gov]

  The degree of visual impairment is quite variable and the phenotype of aniridia can include cases of autosomal dominant keratitis. This is an autosomal dominant disorder inherited directly from a parent who has aniridia. [djo.org.in]

• Suggestibility

  Cell biological findings suggest that OPA1 is regulated by post-translational mechanisms and we would like to hypothesize that loss of OPA1 function might lead to impaired mitochondrial quality control. [publikationen.ub.uni-frankfurt.de]

  Other optic nerve findings suggestive of ADOA include an increased cup-to-disc ratio (48%), temporal gray crescent (31%) and peripapillary atrophy (69%). [healio.com]

  The strong association of OPA1 with membranes suggests its anchoring to the inner membrane [21]. [wikigenes.org]

  Our findings suggest that an analysis of genomic rearrangements is mandatory in the investigation and diagnosis of ADOA. [bmcmedgenet.biomedcentral.com]

  Despite recent data suggesting that the condition is more common than previously thought (the estimated minimum prevalence in a population in northern England is 4.07/100.000, or about 1 in 25.000), ADOA is more rarely reported in Asia. [iovs.arvojournals.org]
