	Axial myopic group	Non-axial myopic group	P
PD0 (mm)	5.67±0.71	5.61±1.40	0.752
PD1 (mm)	4.06±0.64	3.80±0.87	0.045^*
PD10 (mm)	3.40±0.49	3.22±0.66	0.046^*
PD100 (mm)	2.90±0.44	2.98±0.60	0.589
ΔPD1 (mm)	−1.61±0.69	−2.04±0.62	0.008^*
ΔPD10 (mm)	−2.27±0.63	−2.62±0.55	0.016^*
ΔPD100 (mm)	−2.76±0.62	−2.87±0.77	0.173
PD0 – pupil diameter at scotopic condition (0 candelas/m); PD1 – pupil diameter at mesopic condition (1 candelas/m); PD10 – pupil diameter at low photopic condition (10 candelas/m); PD100 – pupil diameter at high photopic condition (100 candelas/m); ΔPD1 – the differences between PD1 and PD0; ΔPD10 – the differences between PD10 and PD0; ΔPD100 – the differences between PD100 and PD0. ^* Significance of difference.
