Experimental: treatment group
14 adult patients in whom the diagnosis of LHON obtained on anamnestic, clinical and ancillary testing / laboratory data. LHON should have occurred for less than 5 years and must be genetically proved with a 3460 or 11778 mitochondrial DNA mutation. Given the mode of transmission, genetic research may have been carried out in a maternal relative. Befizal® 200 mg will be tested for one year |
Drug: Béfizal
600 mf befizal a day for one year |
