AlM:To investigate the visual function in myopia and hyperopia amblyopia whose corrected visual acuity have recovered to normal.METHODS: The visual function of children ( 50 cases ) with amblyopia eyes by binocular vision correction after treatment above 0. 9 was checked. The simultaneous perception, fusion range and distance stereopsis were measured. According to the refractive condition of the children who were divided into group A ( myopia, 20 cases ) and group B ( hyperopia, 30 cases ) . The statistically difference of simultaneous perception, fusion function and stereopsis in two groups was analyzed. RESULTS: Fifteen ( 75%) and twenty - six ( 87%) children got the simultaneous perception in group A and group B respectively, and the differences between two groups were not significant (χ2=0. 454,P>0. 05). Group A had six children ( 30%) and group B had only seven children (23%) with the normal aggregative fusion range, two groups did not show any difference (χ2 =0. 565, P>0. 05). Respectively sixteen (80%),and twenty children ( 67%) had the normal divided fusion range in group A and group B, the recovery rate did not show any significant difference (χ2=0. 740, P>0. 05). Fifteen (50%) and seven ( 35%) patients acquired the far stereoscopic vision in group B and group A respectively, the recovery rate also did not show any significant difference. Normal distance stereopsis of 50 cases had 22 cases ( 44%) , and normal near stereopsis of 50 cases had 13cases ( 26%) Seven (23%) and 6 (30%) children got the normal near stereoscopic vision in group B and group A respectively, and the recovery rate did not show any significant difference (χ2=0. 195, P>0. 05;χ2=0. 295, P>0. 05).CONCLUSlON:After amblyopia treatment, although the children got the normal visual acuity, the binocular vision still can not completely normal in the short term. Myopia and hyperopia factor will not produce significant effect on binocular vision development.
