Leber hereditary optic neuropathy
Leber hereditary optic neuropathy is a disease caused by various mutations in the mitochondrial genome and, as such, is inherited only via the maternal ovum as spermatozoa do not have mitochondria. It usually manifests as sequential binocular acute painless vision loss in sons of carrier mothers. The typical vision loss pattern is decreased visual acuity, with most patients seeing 20/200 or worse, a visual field defect involving the blind spot, and central fixation (cecocentral scotoma).
