方法：观察65例部分调节性内斜患儿术前术后双眼三级视功能的变化以及不同手术年龄组视功能的恢复情况。检测术前术后视觉诱发电位(VEP)的变化。

结果：部分调节性内斜患者术前术后三级视功能的变化差异有统计学意义(Z=7.253，P=0.000)； 手术年龄对术后三级视功能的恢复差异有统计学意义(H=6.739； P=0.034)； 术后P₁₀₀波潜伏期较术前变短，振幅加大(P_潜伏期=0.029； P_波振幅=0.037)。

结论：部分调节性内斜患者术后视功能得到明显改善。手术年龄越早，术后出现高级视功能的可能性越大。

METHODS: Three stages of the binocular visual function and VEP were observed in different ages with 65 cases of partially accommodative esotropia in preoperatively and postoperatively.

RESULTS: The difference in binocular visual function between preoperatively and postoperatively was significant(Z=7.253, P=0.000). The difference in binocular visual function with the difference age of operation was significant(H=6.739, P=0.034). The postoperation latencies were shortened and amplitude values were higher than preoperation(P_latency=0.029, P_amplitude=0.037).

CONCLUSION: The binocular visual function was improved after surgery. The early correction of eye position will benefit to the binocular visual function.
