Objective To investigate the difference of the accommodative amplitude (AMP) and the accommodative facility in the varying degrees of hyperopic amblyopes and the emmetropes.Methods Fifty hyperopic amblyopic children (92 eyes) were divided into the moderate amblyopic group (Group A),the mild amblyopic group (Group B) and the cured amblyopic group (Group C,which could coordinate our inspections).There were 20 emmetropic children (40 eyes) as the control group.The accommodative amplitude of all groups was measured with push-up test,and the accommodative facility was measured with turning over convex and concave lens test. Results The mean value of AMP in Group A was 13.07±1.72D,Group B 14,17±1.60 D,Group C 15.55±1.26D,and the control group 16.09±1.11D.The mean value of the accommodative facility in Group A was 5.77±2.00 cycles/min,Group B 5.13±2.19 cycles/min,Group C 5.06±1.56 cycles/min,and the control group 5.45±2.19 cycles/min.The difference of AMP among the four groups was statistically significant (P ＜0.05),but the difference between Group C and the control group was no statistic meaning (P =0.247).The difference of the accommodative facility among the four groups had no statistic meaning (P =0.723).The AMP of the hyperopic amblyopes was correlated to the corrected visual acuity (r =0.487,P =0.07),and there was no statistic correlation between the AMP and the diopter (r =-0.236,P =0.218). Conclusions AMP of the hyperopic amblyopes is lower than that of the normal children.The accommodation of the hyperopic amblyopes is positively related to the seventy of amblyopia.
