影响原发性先天性青光眼手术后视力的原因分析

目的：探讨影响原发性先天性青光眼术后视力的原因及预防措施。方法：追踪检查５１只接受手术治疗后１０年以上的原发性先天性青光眼的眼压、视力、角膜及杯盘比值等的变化情况。结果：手术不成功的１２只眼视力全部在０．０５以下。手术成功的３９只眼视力在０．１至０．８以上，７只单眼发病者视力都在０．２以下；角膜直径大于１３ｍｍ的２７只眼中２１中眼有Ｈａａｂ线存在；杯盘比值大于０．２以上者１２只眼。结论：手术不成功

The analysis of causes affecting postoperative visual acuity of primary congenital glaucoma

Purpose:To detect the causes affecting postoperative visual acuity of primary congenital glaucoma and preventive measures.Methods:To follow up and examine the changes of intraocular pressure,visual acuity,corneal and C/D of 51 primary congenital glaucoma eyes who had been performed operation for more than ten year.Results:the visual acuity were all less than 0 05 of 12 failure operating eyes,ranged from 0 1 to 0 8 or better of 39 successful operating eyes and less than 0 2 of 7 single illed eyes;21 eyes had haab striae of 27 eyes whose corneal diameter were more than 13 mm;there were 12 eyes whoes C/D were larger than 0 2.Conclusions:Long term intraocular hypertension following failure operation was the basic cause resulting in blindness of primary congenital glaucoma;the visual acuity after successful operation depended on the preoperative damage of optic nerve,the degree of corneal damage and occurrence of postoperative amblyopia.
