目的:观察外路小梁切开术治疗原发性婴幼儿型青光眼的近期和远期疗效。 方法:对2009-01/2011-01间我科用外路小梁切开术所做的23例42眼原发性婴幼儿型青光眼病例随访10~34mo，记录眼压、角膜横径值和杯盘比值。 结果：手术成功率术后1wk时为88%，远期为84%。远期观察眼压较术前明显降低，杯盘比值也较术前改善，角膜横径和术前值相比无明显差异。 结论:外路小梁切开术成功率较高，是治疗婴幼儿型青光眼的较好方法,应作为治疗原发性婴幼儿型青光眼的首选术式。

AIM:To observe the therapeutic effect of extra-trabeculotomy in treatment of primary infantile glaucoma (PIG). METHODS:A total of 23 cases (42 eyes )who were diagnosed with PIG and underwent extra-trabeculotomy in our hospital from January 2009 January 2011 were retrospectively analyzed. The intraocular pressure, corneal diameter and cup-disk ratio were observed. The follow-up period was 10-34 months. RESULTS:At the postoperative 1 week, the successful rate of extra-trabeculotomy was 88%. For those eyes with the follow-up more than 10 months, the intraocular pressure was significantly decreased, the cup-disk ratio was reduced, the corneal diameter unchanged and the successful rate was 84%. CONCLUSION:The glaucoma surgery of extra-trabeculotomy is an effective and optimal method for PIG for its high successful rate.
