Indirect Comparison of Lenadogene Nolparvovec Gene Therapy Versus Natural History in Patients with Leber Hereditary Optic Neuropathy Carrying the m.11778G>A MT-ND4 Mutation
CONCLUSION: The efficacy of lenadogene nolparvovec in improving visual acuity in MT-ND4 LHON was confirmed in a large cohort of patients, compared to the spontaneous natural history decline. Bilateral injection of gene therapy may offer added benefits over unilateral injection.
Analysis of Human Clinical Mutations of Mitochondrial ND1 in a Bacterial Model System for Complex I
The most common causes of mitochondrial dysfunction and disease include mutations in subunits and assembly factors of Complex I. Numerous mutations in the mitochondrial gene ND1 have been identified in humans. Currently, a bacterial model system provides the only method for rapid construction and analysis of mutations in homologs of human ND1. In this report, we have identified nine mutations in human ND1 that are reported to be pathogenic and are located at subunit interfaces. Our hypothesis…
Developments in the Treatment of Leber Hereditary Optic Neuropathy
PURPOSEOF REVIEW: To outline the current landscape of treatments for Leber hereditary optic neuropathy (LHON) along the therapeutic delivery pipeline, exploring the mechanisms of action and evidence for these therapeutic approaches.
Leber’s hereditary optic neuropathy companied with multiple-related diseases
CONCLUSION: Leber’s hereditary optic neuropathy can be accompanied with multiple-related diseases, especially different subtypes of ON, which were also exhibited with IOIS and compression optic neuropathy for the first time in this cohort. This condition may be a distinct entity with an unusual clinical and therapeutic profile.
Clinical application of multicolor imaging in Leber hereditary optic neuropathy
CONCLUSION: As an adjunct to SD-OCT, the MC image, particularly the GR and BG can delineate RNFL more effectively than CFP. The MC image may be a useful adjunct to OCT for detecting or monitoring never fiber bundle defects, providing inexpensive and rapid methods that can quickly identify patients with high suspicion of LHON.
Case report: Long-term follow-up of two patients with LHON caused by DNAJC30:c.152G>A pathogenic variant-case series
CONCLUSIONS: Presented are two autosomal recessive LHON (arLHON, OMIM:619382) cases with the same DNAJC30:c.152G>A pathogenic variant and different degrees of spontaneous visual recovery despite progressive RNFL thinning during a long-term follow-up. This mutation should be screened in every atypical LHON patient.

Neuroimaging in Leber Hereditary Optic Neuropathy: State-of-the-art and future prospects
Leber Hereditary Optic Neuropathy (LHON) is an inherited mitochondrial retinal disease that causes the degeneration of retinal ganglion cells and leads to drastic loss of visual function. In the last decades, there has been a growing interest in using Magnetic Resonance Imaging (MRI) to better understand mechanisms of LHON beyond the retina. This is partially due to the emergence of gene-therapies for retinal diseases, and the accompanying expanded need for reliably quantifying and monitoring…
Childhood-Onset Leber Hereditary Optic Neuropathy-Clinical and Prognostic Insights
CONCLUSIONS: Children who lose vision from LHON before the age of 9 years have a better visual prognosis than those who become affected in later years, likely representing a “form frustre” of the disease.
The care of patients with Leber’s hereditary optic neuropathy/patient associations
We present the therapeutic-rehabilitative then social management of a visually impaired patient by Leber hereditary optic neuropathy (LHON). The different structures that can intervene are explained. Two typical medico-social situations are detailed, namely an LHON occurring in a student, and in an adult who works.
