Elamipretide Topical Ophthalmic Solution for the Treatment of Subjects With Leber’s Hereditary Optic Neuropathy: A Randomized Trial
CONCLUSIONS: Elamipretide treatment was generally well tolerated with no serious adverse events reported. Although this study did not meet its primary BCVA efficacy endpoint, improvements across assessments on visual function during the OLE, and the post-hoc findings of the HVF central region, were encouraging and require further exploration.
Leber’s Hereditary Optic Neuropathy (LHON): Clinical Experience and Outcomes after Long-Term Idebenone Treatment
CONCLUSIONS: Our study demonstrated positive results with long-term Idebenone use. Contrary to medical literature, our female patient had a favorable evolution, despite the delayed diagnosis.
Leber Hereditary Optic Neuropathy (LHON) in Patients with Presumed Childhood Monocular Amblyopia
CONCLUSIONS: This report shows three different scenarios of presentation of LHON in patients with presumed uniocular amblyopia from childhood. In such cases, the diagnosis may be difficult, and detailed structural and functional evaluation of the optic nerve head is necessary to assess whether an earlier LHON episode was misdiagnosed as amblyopia or whether LHON presented bilaterally on both eyes whilst only being noticed in the previously good eye.
Approaches to the epidemiology of NOHL in the region of Madrid: Survey of neuro-ophthalmologists
CONCLUSION: This work constitutes the first approach to the epidemiology of this disease in Spain. The prevalence of LHON in the region of Madrid, is probably lower than that reported in the literature in other regions. The prevalence and the incidence were homogeneously low in the 26 studied areas.
A rare, likely pathogenic variant causing Leber’s hereditary optic neuropathy in three-generation females of an African-American family
CONCLUSIONS AND IMPORTANCE: Our patients’ presentation stresses the importance of including LHON in the differential diagnosis in females presenting with unexplained bilateral, painless, severe visual loss. The OCT finding of profound GCC thinning with relatively preserved pRNFL thickness can be a red flag for LHON. A collaboration with genetic specialists to utilize expanded gene sequencing may greatly enhance our ability to identify rare pathogenic variants.
Leber hereditary optic neuropathy presenting as bilateral visual loss and white matter disease
Leber hereditary optic neuropathy (LHON) is a rare maternally inherited mitochondrial disorder that typically affects young male adults in their second and third decades of life. It usually manifests as painless, subacute, progressive, bilateral vision loss, with more than 90% of affected individuals losing their vision before age 50. Compared with other diseases that cause optic neuritis (multiple sclerosis or neuromyelitis optica spectrum disorders), LHON has worsening visual function in the…
Recessive MECR pathogenic variants cause an LHON-like optic neuropathy
CONCLUSION: We report the first family with homozygous MECR variant causing an LHON-like optic neuropathy, which pairs the recent MCAT findings, reinforcing the impairment of mtFAS as novel pathogenic mechanism in LHON.
Coenzyme Q10 trapping in mitochondrial complex I underlies Leber’s hereditary optic neuropathy
How does a single amino acid mutation occurring in the blinding disease, Leber’s hereditary optic neuropathy (LHON), impair electron shuttling in mitochondria? We investigated changes induced by the m.3460 G>A mutation in mitochondrial protein ND1 using the tools of Molecular Dynamics and Free Energy Perturbation simulations, with the goal of determining the mechanism by which this mutation affects mitochondrial function. A recent analysis suggested that the mutation’s replacement of alanine A52…
Leber Hereditary Optic Neuropathy Gene Therapy: Longitudinal Relationships Among Visual Function and Anatomical Measures: LHON Gene Therapy: Visual Function and Anatomical Measures
PURPOSE: To assess longitudinal relationships among visual function and anatomical measures of gene therapy in G11778A Leber hereditary optic neuropathy (LHON).
