Brief Summary

Leber's hereditary optic neuropathy (LHON) is a rare mitochondrial genetic disorder characterized by optic nerve atrophy due to the degeneration of retinal ganglion cells, which leads to acute visual loss. Males are more likely to develop optic neuropathy than women. They experience blurring or clouding of vision in one eye. The fellow eye develops similar symptoms sequentially with a delay of weeks. This sudden vision loss has devastating consequences on the life course of young men, with the impact of LHON on their quality of life and loss of independence. Yet, data describing the impacts of LHON on the life-course of patients is lacking, with very little data available in the literature. This study aims to understand the life of patients living with LHON disease through the analysis of the impact of LHON on the quality of life and loss of independence of patients living in France and to accurately describe the consequences of the disease on their social, familial and professional life.
