What is Lebers hereditary optic neuropathy (LHON)?
LHON causes a painless loss of central vision between 12 and 30 years of age. Both eyes are affected at the same time. Males will not pass the gene to any of their children, but females with the mutation will pass it to all of their children, regardless of whether they are sons or daughters.
