Leber’s Hereditary Optic Neuropathy (LHON)
In October 2006, Tucker was diagnosed with Leber’s Hereditary Optic Neuropathy (LHON), an inherited and quite rare form of progressive vision loss. One of Tucker’s goals is to raise awareness of LHON.
Leber’s hereditary optic neuropathy (LHON) is an inherited form of vision loss caused by mutations in certain mitochondrial genes (also known as maternal inheritance). Although LHON usually presents in a person’s teens or twenties, cases also may appear in early childhood or later in adulthood. For reasons that remain unknown, males are affected at a much higher rate than females.
Interestingly, there is often no family history of LHON in people who develop the condition. However, all females with a mitochondrial DNA mutation – even those who do not have any signs or symptoms – will pass the genetic change on to their children. Males cannot pass LHON to their children.
What are the symptoms of LHON, and what is the progression of the disorder?
Blurring and clouding of vision usually are the first symptoms of this disorder. Vision problems may begin in one eye or simultaneously in both eyes. Over time, vision in both eyes worsens, with a severe loss of sharpness and color vision. This condition mainly affects central vision, which is needed for detailed tasks such as reading, driving and recognizing faces. Vision loss results from the death of cells in the nerve that relays visual information from the eyes to the brain (the optic nerve).
No two people with LHON experience the same visual impairment. Although central vision gradually improves in a small percentage of cases, in most cases – as in Tucker’s case – the vision loss is profound and permanent. The prognosis for those affected is almost always that of continued very severe visual loss.
How common is LHON?
The prevalence of LHON in most populations is unknown. In a study by Man, Griffiths et al in The American Journal of Human Genetics (2003), it was found to affect 1 in 30,000 to 50,000 people in northeast England and Finland. However, current estimates state that more than 50% of men and more than 85% of women with a mutation never experience vision loss or related medical problems tied to LHON.
Is there a cure or treatment for LHON?
At present, there is no cure for LHON, and no experimental treatments have been proven effective in clinical trials. Reports of cure with drugs in isolated LHON cases may be spontaneous recoveries, which are known to happen in some genetic mutations more than others.
