青光眼高危因素与阈值视野的相关性

Relationship between the high risk factors of glaucoma and threshold visual fields

目的 探讨原发性青光眼高危因素与自动静态阈值视野改变之间的关系。方法 5 5 0例 (10 43眼 )可疑青光眼患者 ,根据诊断的主要因素 ,分为浅前房组、异常杯盘比组、高眼压组及症状性疑青光组组 ,分别接受Octopusl- 2 - 3型全自动视野的检查。结果 原发性青光眼的高危因素依次为异常杯盘比 (45 .8% ) ,高眼压(30 .4% ) ,症状组 (2 1.3% ) ,浅前房组 (2 .5 % )。其静态阈值视野改变的阳性率分别为 6 2 .8%、6 0 .5 %、5 9.0 %和73.9% ,各组间阳性率差异无显著性 (P >0 .0 5 )。结论 仔细检查所有可疑青光眼患者的静态阈值视野并随访其改变 ,对青光眼的早期诊断具有重要的意义。

Objective To observe relationship between high risk factors of primary glaucoma and the changes of automated static threshold visual fields.Methods According to the leading causes of glaucoma suspects,550 cases (1043 eyes) were divided into shallow anterior chamber,abnormal cup-to-disc ratio,high intraocular pressure and symptom group.Static threshold visual fields were detected respetively in all patients with Octopus 1-2-3 automated perimeter.Results The leading causes of glaucoma suspects were abnormal cup-to-disc ratio(45.8%),high intraocular pressure(30.4%),sympton group(21.3%) and shallow anterior chamber(2.5%).The corresponding abnormal static threshold visual fields rations were 62.8%,60.5%,59.0%and 73.9%.There were no differences among these groups(P>0 05) Conclusion It was important for early diagnosis of glaucoma to detect all glaucoma suspects and follow up their changes of static threshold visual fields
