Front Neurol 2021 26;12:651639. Epub 2021 May 26.

Neuro-ophthalmology Department, Hôpital Fondation Rothschild, Paris, France.

Leber hereditary optic neuropathy (LHON) is a maternally inherited mitochondrial disease that specifically targets the retinal ganglion cells by reducing their ability to produce enough energy to sustain. The mutations of the mitochondrial DNA that cause LHON are silent until an unknown trigger causes bilateral central visual scotoma. After the onset of loss of vision, most patients experience progressive worsening within the following months. Read More
