Noninvasive Ophthalmic Imaging Measures Retinal Degeneration and Vision Deficits in Ndufs4−/− Mouse Model of Mitochondrial Complex I Deficiency
Avrutsky MI, Lawson JM, Smart JE, Chen CW, Troy CM
Mitochondrial complex I disorders are a heterogeneous group of rare inherited diseases caused by mutations affecting proteins in the mitochondrial electron transport chain. Neurological and ophthalmic pathologies are common to many forms of complex I deficiency, due to the high energy demands of central nervous system tissues. Avrutsky et al characterized one such mouse model, carrying a mutation in Ndufs4 (NADH:ubiquinone oxidoreductase Fe-S pro-tein 4), which shows fast retinal degeneration within only a few weeks. They show that a range of non-invasive techniques (OCT for structural changes, ERG for electrophysiological properties, and OMR with our OptoDrum for behavioral assessment) can capture relevant measures of disease progression.
