方法：纳入2007-03/2012-10间本院28例先天性眼球震颤术后残余代偿头位患儿，其中男19例，女9例，年龄4～20(平均8.7)岁。根据病史和临床检查结果，所有患儿均配戴适当度数的压贴三棱镜减轻术后残余代偿头位，配镜后每2mo复查一次，询问是否有无头晕等不适症状，检查矫正视力，检查眼位及代偿头位改善情况。

结果：患儿27例坚持随访，1例失访。(1)症状：26例患儿戴镜期间无头晕、视物变形等不适，戴镜舒适率为96%(26/27)。(2)视力改善情况：患儿矫正视力由戴镜前0.5±0.3上升至戴镜后0.6±0.2，但差异无统计学意义(P>0.05)。(3)患儿戴镜前残余代偿头位5°～35°，平均(9.6±2.2)°，戴镜后残余代偿头位2°～35°，平均(5.7±2.2)°，戴镜前后差异有统计学意义(P<0.05)。18例患儿残余代偿头位基本消失(<5°)，占67%(18/27)，8例改善(5°～10°)，占30%(8/27)，残余代偿头位改善率达96%(26/27)。

结论：压贴三棱镜是一种治疗先天性眼球震颤术后残余代偿头位的一种有效的方法，可以改善外貌，增加自信心，最终提高患儿的生活质量。

METHODS: From March 2007 to October 2012, 28 congenital nystagrnus children with residual compensatory head posture after surgery including 19 males and 9 females were admitted to our department. The average age of these children was 8.7 years old, ranging from 4 to 20. All of them were treated by pressing triple prism. Improvement of vision and compensatory head posture were used to evaluate the efficacy during the follow up.

RESULTS: Twenty-seven children adhere to follow-up. One child failed to follow-up. 1)Symptoms: most children did not complain visual distortion, dizziness when wearing glasses. Comfort rate was reaching 96%(26/27). 2)Visual improvement: vision rose from(0.5±0.3)to(0.6±0.2)after wearing glasses, however, the difference was not statistically significant(P>0.05). 3)Improvement of compensatory head posture: compensatory head posture was decreased after wearing glasses, from(9.6±2.2)° to(5.7 ± 2.2)° with significantly difference(P<0.05). Among them, 18 children(67%)had almost disappearance of residual compensatory head(<5°), 8(30%)had improvement(5°～10°). The improvement rate was 96%(26/27).

CONCLUSION: Pressing triple prism is an effective way to cure residual compensatory head posture after congenital nystagmus surgery.
