Evaluation of Vision-Related Quality of Life in Chinese Patients With Leber Hereditary Optic Neuropathy and the G11778A Mutation

Objective: To assess quality of life (QoL) measures in Chinese Leber hereditary optic neuropathy (LHON) patients with the G11778A mutation. Methods: Chinese LHON patients with the G11778A mutation were prospectively evaluated using the Visual Function Index (VF-14) at 6 months, 1 year, and 3 years after the involvement of the second eye. Patients who completed the VF-14 at all 3 follow-up time designations were included in the analysis. Results: Fifty-five patients met the inclusion criteria. The median age of patients when their vision was bilaterally affected was 16.3 years old (interquartile range: 13.9–18.3 years). In our patient cohort, 89.1% (n = 49) were male, and the ratio of males to females was 8.2:1. The median logMAR visual acuity was 2.0 (interquartile range: 1.0–2.6). The mean VF-14 scores of patients with LHON at 6-month, 1-year, and 3-year follow-ups were 18.0 ± 19.2 (range 0–85.4), 19.9 ± 20.0 (range 0–85.4), and 20.7 ± 20.2 (range 0–85.4), and the differences were statistically significant (P
