Reviews of LHON treatment prospects:

Somewhat against the grain of the narrow drug centred 'silver bullet' paradigm currently dominating medical research and therapy is another call for long overdue research on the safety and efficacy of diet therapy. For example, not enough research on ketogenic diets in LHON has occurred since Douglas Wallace's proposal in 2010, 'Mitochondrial Energetics and Therapeutics', where he outlines and critiques metabolic therapies for mitochondrial diseases to date and discusses the revival of ketogenic diets and a more systemic approach as potential therapy. This approach is gaining popularity in many major diseases. So it is important for LHON carriers to know if this approach is safe for them and possibly preventative for various illness including LHON. Maybe a mouse fodder trial is the next step? Maybe survey of insulin resistance in LHON carriers and affected? Coffee anyone? Since we know Efficient mitochondrial biogenesis drives incomplete penetrance in Leber’s hereditary optic neuropathy, shouldn't we find all avenues to support it?

Some research on the benefits of ketosis on the optic nerve and nervous system (then caution followed by coffee):

Orphanet Journal of Rare Diseases volume 14, Article number: 150 (2019). Ketogenic treatment reduces the percentage of a LHON heteroplasmic mutation and increases mtDNA amount of a LHON homoplasmic mutation.
