可疑青光眼杯盘比值与静态阈值视野改变的观察

The relationship between C/D and the static threshold visual field

目的 :观察静态阈值视野改变与可疑青光眼患者的年龄及临床判定的杯盘比大小的关系。方法 :对 2 0 7例 (3 90眼 )青光眼可疑患者 ,分为杯盘比值大于等于 0 6组和小于 0 6组 ;并按年龄分为 3 0岁以上组和 3 0岁以下组 (包括 3 0岁 ) ,采用Octopus 1～ 2～ 3型全自动静态阈值视野计分别进行了阈值视野测定。结果 :杯盘比值大于等于 0 6组视野异常率 (4 4 2 % )高于杯盘比值小于 0 6组 (3 9% ) ,两组相比差异有显著性 (P <0 0 5 )。3 0岁以下组 (包括 3 0岁 )视野异常率 (3 6 8% )与 3 0岁以上组 (4 5 2 % )相比差异无显著性 (P >0 0 5 )。结论 :可疑青光眼患者的年龄对阈值视野的改变不产生有意义的影响。从阈值视野改变的角度 ,杯盘比值 0

Objective:To observe the relationships between the changes in threshold of static visual field to the cup to disc ratio evaluated by the clinicians,and to the ages of glaucoma suspects. Methods:According to the age and vision,suspects were divided into more than 30 years and less than 30 years groups.According to the ratio of cup to disc,suspects were divided into more than 0.6(including 0 6) and less than 0 6 groups.Threshold visual fields were detected in 390 eyes of 207 glaucoma suspects. Results:The rate of abnormal visual field in more than 0 6 group (44 2%) was higher than that in less than 0.6 group (39%,P<0 05).There was no difference in more than 30 years group (45 2%) and less than 30 years group (36 8%,P>0 05). Conclusions:The ages of glaucoma suspects may not influence the results of static threshold visual field.From the static threshold visual field,it is practical to identify C/D 0 6 as the screening standard of glaucoma.
