蓝/黄视野检查法对原发性开角型青光眼正常半侧视野的检测

Blue-on-yellow perimetry in examination of primary open-angle glaucoma with hemifield defect

目的 探讨蓝/黄视野检查法( blue-on-yellowperimetry,BYP)检测早期青光眼视野异常的能力。方法 对普通白/白视野检查法(white on-white-perimetry,WWP)检查结果仅为半侧视野异常的23例23眼原发性开角型青光眼患者进行BYP检查。结果 BYP检查的平均光敏感度、平均缺损及偏离缺失值与WWP检查的平均光敏感度、平均缺损及偏离缺失分别呈明显正相关(r 分别为0.597 0,0.787 9和0.850 7,P<0.000)。WWP检查异常的半侧视野中,BYP检查的视野缺损点数明显多于WWP检查的缺损点数(t=2.1535,P=0.018 4);WWP检查正常的半侧视野中,有52.17%(12/23)的患者出现BYP检查结果异常。结论 BYP检查法能发现WWP检查法尚不能检出的视野缺损。

Objective To determine whether blue-on-yellow perimetry(BYP) can find visual field defect of early glaucoma which can not be found with white-on-white perimetry(WWP).Methods Twenty-three eyes of 23 patients with primary open-angle glaucoma and hemifield defect detected with WWP were tested with BYP.Results The significant positive correlation were found between the mean sensitivity (MS),mean defect(MD),loss variance(LV) with BYP and those with WWP(r=0.597 0,0.787 9 and 0.850 7,P<0.000).The number of the visual field defective points field with BYP was more than that with WWP in the hemifield that the visual field defect was detected with WWP(t=2.153 5,P=0.018 4).The 52.17%(12/23) patients showed the BYP visual field defect in the hemifield that no visual field defect was detected with WWP.Conclusion BYP can find visual field defect of early glaucoma which can not be found with WWP.
