Retinal nerve fiber layer thickness and visual field at each measure points.

	Average RNFLT (μm)	value	Average MD (dB)	value
1 M before	90.5 ± 10.4		−0.89 ± 1.08
1 D before	91.0 ± 10.0		−0.85 ± 0.74
1 M after	91.3 ± 10.2	0.98	−0.54 ± 1.09	0.21
3 M after	91.3 ± 10.2	0.96	−0.40 ± 0.72	0.06

M: month; D: day; RNFLT: retinal nerve fiber layer thickness; MD: mean deviation; value is compared with 1 D before.
