【摘要】 目的　探讨不同年龄组外斜视手术后立体视觉恢复的情况。方法　对 85例外斜视应用同视机 ,立体视觉检查图及三棱镜分别进行术前、术后立体视觉阈值及斜视度检查 ,分析其结果。结果　 85例远、近立体视觉手术后与手术前比较差异均有显著性意义 (P <0 .0 5 ) ,发病年龄 ,融合范围与术后双眼视觉的重建差异均有显著性意义 (P <0 .0 5 )。结论　外斜视的发病年龄 ,手术年龄及斜视角的大小 ,融合范围的大小直接影响立体视觉功能的恢复更多还原

【Abstract】 Objective The stereopsis vision at the different age gr oups after concomitant extropia operation was studied.Me thods Threshold of stereopsis and the grade of the strabismus of the 85 cases with concomitant extropia were separately analyzed before and after the operation.Results (1)Significant difference was shown in the far and near stereopsis vision befo re and after the operation( P<0.05);(2) Significant diffe rences were also showed between different ages and range of fusion.Conclusion Age, operation timing and the range of fusion directly influence the recover y of the stereopsis vision.更多还原
