[Brain magnetic resonance imaging features in Leber's hereditary optic neuropathy].

Leber's hereditary optic neuropathy (LHON) is the most common inherited mitochondrial disease, characterized by the development of bilateral partial optic nerve atrophy. Modern neuroimaging technologies enable the acquisition of high-quality images, allowing for the evaluation of all structural components of the orbits, including the optic nerve. Consequently, the relevance of performing magnetic resonance imaging (MRI) in patients with LHON has increased. MRI is an essential tool for clarifying the topographic localization and the extent of the pathological process in LHON, both within and beyond the visual system. Correlating MRI findings with the clinical manifestations of LHON can help in predicting disease progression and assessing the effectiveness of therapy.
