Vision loss in dominant optic atrophy is due to optic nerve fiber loss from mitochondria dysfunction. Dominant optic atrophy is associated with mutation of the OPA1 gene [9] found on chromosome 3, region q28-qter. Also, 5 other chromosomal genes are described as causing optic atrophy: OPA2 (x-linked), OPA3 (dominant), OPA4 (dominant), OPA5 ...
While optic neuropathy cannot be outright cured, there are surgical options to alleviate pain and symptoms associated with such diseases. The Endoscopic Endonasal Approach method (EEA) is a method of relieving pressure associated with tumors formed in the brain that press upon the optic nerve. It is a minimally invasive surgery.
The mother was the most affected: her phenotype consisted of additional features her son did not suffer from, including severe vision impairment and bilateral optic nerve atrophy. [ 32 ] The fourth case report was written by Hogewind et al. , whose patients were three affected members of a two-generation Dutch family (two brothers and their ...
PEHO syndrome (progressive encephalopathy with edema, hypsarrhythmia and optic atrophy) is an autosomal recessive and dominant, progressive neurodegenerative disorder that starts in the first few weeks or months of life. Early symptoms include infantile spasms, hyparrhythmia, and seizures, and optic atrophy.
Non-arteritic anterior ischemic optic neuropathy (NAION) is a medical condition characterized by loss of vision caused by damage to the optic nerve as a result of ischemia, or insufficient blood supply. The key symptom of NAION is optic disc swelling, which typically resolves within 2 months, but often leads to optic atrophy. The likelihood of ...
Wolfram syndrome, also called DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness), is a rare autosomal-recessive genetic disorder that causes childhood-onset diabetes mellitus, optic atrophy, and deafness as well as various other possible disorders including neurodegeneration.
Bosch–Boonstra–Schaaf optic atrophy syndrome is a rare autosomally inherited condition characterised by developmental delay, intellectual disability and decreased visual acuity. [ 2 ] [ 3 ] [ 4 ] Presentation
Treatment is dependent upon diagnosis and the stage at which the diagnosis is secured. For toxic and nutritional optic neuropathies, the most important course is to remove the offending agent if possible and to replace the missing nutritional elements, orally, intramuscularly, or intravenously. If treatment is delayed, the injury may be ...
