Abstract/OtherAbstract:
Mitochondrial disorders are a group of clinically heterogeneous diseases, commonly defined by lack of cellular energy due to genetic defects of oxidative phosphorylation (OXPHOS). Ocular involvement is a prominent clinical feature of mitochondrial disease. This can manifest as optic nerve dysfunction specifically involving retinal ganglion cells as typified by Leber hereditary optic neuropathy (LHON), or progressive external ophthalmoplegia (PEO) and ptosis involving the extraocular muscles which is commonly associated with either primary mitochondrial DNA (mtDNA) mutations or acquired mtDNA defects secondary to a nuclear genetic disorder of mtDNA maintenance. In this short review, we will outline the unique characteristics of mitochondrial genetic disease and its investigation with reference to the clinical features and molecular genetic abnormalities underlying mitochondrial ophthalmological disease.
