QZS－Ⅲ型自动视野计早期诊断青光眼

Early Diagnosis of Glaucoma with QZS-Ⅲ Automatic Perimeter

用ＱＺＳ－Ⅲ型自动视野计阈值检查法与投影视野计检查法检查可疑青光眼５２例（１０４眼），并就其检出效果作对照分析。自动视野计检出８６眼有视野改变，其中青光眼早期视野改变７５眼，非青光眼视野改变（生理盲点扩大）１１眼，未查出视野改变为１８眼；投影视野计检查仅３２眼查出青光眼早期视野改变，未查出视野改变７２眼。根据临床观察并结合患者眼压、房角、激发试验和视乳头的情况，自动视野计检查组有３４眼诊断为青光眼，而投影视野计检查组有１４眼诊断为青光眼，两者比较有显著性差异。说明自动视野计敏锐度强，可及时为可疑青光眼和早期青光眼的诊断提供重要依据。

One hundred and four eyes in 52 cases of suspicious glaucomawere examined with QZS-Ⅲ automatic perimeter(AP)and projection perimeter(PP)simultaneously.Changes in visualfield were found in 86 eyes examined with AP,including early glaucoma changes in 75 eyesand enlarged physiological scotoma in 11 eyes;and were found only 32 eyes with PP. Incombination with analyses of intraocular pressure,iridocorneal angle,results of provocativetests and surface of optic disc,34 eyes(with AP)and 14 eyes(with PP)were diagnosed asglaucoma. There was significant difference between the results detected with AP and PP,indicating that AP is more sensitive than PP and can offer important basis for the diagnosisof early glaucoma.
