方法：弱视儿童78例中，随机分为视功能训练组36例70眼，对照组42例67眼。经弱视治疗双眼视力均达到0.9以后，观察两组在随访6，12，24，36mo后的视力回退情况。

结果：6mo后的轻、中、重度弱视视功能训练组与对照组回退率均为0，差异无统计学意义； 12mo后视功能组轻、中、重度弱视回退率与对照组之间差异均无统计学意义； 24，36mo后视功能组轻度弱视回退率与对照组之间差异无统计学意义(P=0.269，0.269)； 中度弱视回退率与对照组之间差异有统计学意义(P=0.004，0.002)； 重度弱视回退率与对照组之间差异无统计学意义。

结论：视功能训练能降低中度儿童弱视治疗中的回退率，能有效的巩固中度儿童弱视视力正常后的治疗效果。但对于轻度和重度儿童弱视无明显疗效。

METHODS: Totally 78 amblyopic children were divided into two groups: visual function training group(n=36, 70 eyes)and control group(n=42, 67 eyes). The rollback situation of the two groups in 6, 12, 24 and 36 months were observed after visual acuity reached 0.9 during treatment.

RESULTS: The rollback rates were both 0 in visual function training group and control group with different degrees of amblyopia after 6 months. There was no significant difference in rollback rate between the 2 groups with different degrees of amblyopia after 6 and 12 months. There was no significant difference in rollback rate between the two groups with mild amblyopia after 24 and 36 months(P=0.269, 0.269). However, the rollback rate in training group with moderate amblyopia was significantly different from in control group after 24 and 36 months(P=0.004, 0.002). There was no significant difference in rollback rate between the two groups with severe amblyopia after 24 and 36 months.

CONCLUSION: Visual function training can reduce the rollback rate and consolidate the effect of amblyopic treatment effectively for children with moderate amblyopia. However, the effect is not as good for children with mild and severe amblyopia.
