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

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

Subjects (eye)	Control group 60 (118)	Subclinical group 50 (98)	Abnormal goup 14 (28)	P value^a
BCVA (LogMar)	0.00 (0.00–0.00)	0.00 (0.00–0.10)	0.95 (0.1–1.45) ^bc	0.001
VFs (MD, dB)	−0.62(−1.29—0.35)	−0.98(−1.98–0.45)	−6.08(−11.48–4.98)^bc	0.021

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