Table 3 Comparison of visual functions between subclinical, abnormal and control groups. Median (IQR)

From: Analysis of structural injury patterns in peripapillary retinal nerve fibre layer and retinal ganglion cell layer in ethambutol-induced optic neuropathy

Subjects (eye) Control group 60 (118) Subclinical group 50 (98) Abnormal goup 14 (28) P valuea
BCVA (LogMar) 0.00 (0.00–0.00) 0.00 (0.00–0.10) 0.95 (0.1–1.45) bc 0.001

  1. BCVA Best corrected visual acuity, VFs Visual field sensitivity, MD Mean deviation
  2. aComparison among the three groups by 1-way analysis of variance
  3. bSignificant difference compared with the control group by post hoc multiple comparison
  4. cSignificant difference compared with the subclinical group post hoc multiple comparison
