“…Thickness of peripapillary RNFL decreased signi cantly in four quadrants during disease progression. In the chronic phase, peripapillary RNFL thickness decreased slightly by OCT [17]. As we all see, the disadvantage of OCT is that it only measures 4 sectors.…”

Purpose To analyse the peripapillary retinal nerve fiber layer (RNFL) by optical coherence tomography angiography (OCTA) in Leber’s hereditary optic neuropathy (LHON) in m.11778G > A mutation in the MT-ND4 gene. Method This work is a retrospective study and included 24 eyes from 12 patients with LHON. Fifteen healthy people with 30 eyes matched to the age and gender of the patient group were recruited as a normal control group. All of the LHON patients with m.11778G > A mutation were diagnosed by genetic testing. Peripapillary RNFL included 360-degree average and eight sectors (superotemporal, superonasal, nasoupper, nasolower, inferonasal, inferotemporal, temporolower, temporoupper) were measured by OCTA. Results Compared with control group, peripapillary RNFL in LHON group were significant thinner in average thickness (p < 0.01) and eight sectors (all p < 0.01). Conclusions OCTA results confirm that peripapillary RNFL is significant thinner in LHON patients. OCTA can evaluate eight sectors RNFL damage on LHON patients.
