Rare Diseases

Leber Hereditary Optic Neuropathy (LHON)

As individuals, we rely on sight more than any other sense to navigate the world. LHON is a rare disease that leads to sudden and irreversible loss of vision, typically in the pivotal years of adolescence and early adulthood. While coping with the emotional and social costs of sudden blindness, patients must also bear the financial burden associated with adaptive technologies, specialized training, accessibility modifications, rehabilitation, psychological support, reduced workforce participation, and changes in employment outlook. In the US alone, the broader economic impact of blindness surpasses $16,000 per patient per year.

While the genetic cause of LHON is generally understood, the mechanisms driving its progression have only partially been discovered. As an optic neuropathy, mitochondrial disease, and neurodegenerative disease, LHON presents opportunities to uncover shared and cross-cutting disease mechanisms. However, progress has been constrained by limited funding and the small size of the research and clinical communities. To transform the LHON therapeutic landscape for the LHON community will require a more expansive and coordinated effort to bridge these gaps and unlock the full potential of LHON research.

Our Work

Partnership with the LHON Collective

SPARC conducted a landscape analysis to identify key funding gaps and strategic opportunities to accelerate progress in LHON research and care. SPARC published a report Giving Smarter Guide for LHON to identify where philanthropic investment could drive the most impact and help build a more sustainable and collaborative research ecosystem.
