In this study, the group taking idebenone 900 mg per day for 24 weeks showed a slight improvement in visual acuity compared to the placebo group, though the difference was not statistically significant. But patients taking idebenone were protected from further vision loss, whereas the placebo group had a steady decline in visual acuity. Further, people taking idebenone demonstrated preservation of color vision and persistence of the effects of idebenone 30 months after discontinuing therapy. A retrospective analysis of 103 LHON patients by Carelli et al. builds upon these results. This study highlighted that 44 subjects who were treated with idebenone within one year of onset of vision loss had better outcomes, and that these improvements persisted for years.Idebenone, combined with avoidance of smoke and limitation of alcohol intake, is the preferred treatment protocol for people with LHON. Idebenone doses are prescribed to be taken spaced out throughout the day, rather than all at once. For example, to achieve a dose of 900 mg per day, patients take 300 mg three times daily with meals. Idebenone is fat-soluble, and may be taken with a moderate amount of dietary fat in each meal to promote absorption. It is recommended that patients on idebenone also take vitamin C 500 mg daily to keep idebenone in its reduced form, as it is most active in this state. Estrogen Replacement Therapy
Estrogens have been shown to have a protective role in the pathogenesis of LHON.
Bromoderma is a skin condition characterized by an eruption of papules and pustules on the skin. : 135   It is caused by hypersensitivity to bromides, such as those found in certain drugs. There is at least one reported case of bromoderma caused by excessive consumption of a soft drink (Ruby Red Squirt) containing brominated vegetable oil. See also
