Table 1. Results of neuro-ophthalmologic assessment in patients with Leber's hereditary optic neuropathy.
| Left Eye | Right Eye | |
| Mean visual acuity (range) | 1.33 (3-0) | 1.14 (3-0) |
| Average mean deviation (range) (dB) | −15.73 (−0.43 to −32.61) | −15.48 (−1.48 to −33.35) |
| Average PRNFL thickness (range) (µm) | 56.9 (33.1–89.3)* | 56.5 (38.1–80.4)* |
| Temporal PRNFL thickness (range) (µm) | 36 (31–47)* | 49 (19–95)* |
Abbreviations: PRNFL = peripapillary retinal nerve fiber layer, SD = standard deviation.
*Below normal (<5th percentile) as compared with a database of age-matched control subjects. See text for further details.
