可疑视野缺损眼的蓝/黄视野检查

目的：探讨蓝／黄视野检查法(B／YP)在可疑视野缺损眼中的应用价值。方法：对42例(42眼)白／白视野检查法(W／WP)有可疑视野缺损的患者进行B／YP检查，并对两种视野检查法的视野指数和阈值点对点进行相关分析。结果：42只眼中3只眼(7．14％)B／YP检查视野正常，39只眼(92．86％)显示有B／YP视野异常。B／YP与W／WP检查的视野指数(平均敏感度、平均缺损和偏离缺失)之间无明显相关性，两种视野检查法半数以上的阈值点间有一定的相关性。结论：B／YP检查视野的敏感性高于W／WP检查法。对B／YP检查视野异常且异常部位与W／WP检查可疑视野异常部位一致的患者应密切随访观察。

Blue-on-yellow Perimetry in Patients of the Suspected Visual Field Defect

Objective To evaluate the application value of blue -on -yellow perimetry ( B/YP) in the suspected visual field defect eyes. Methods The B/YP were tested by Octopus 101 automated perimetry in 42 suspected visual field defect patients (42 eyes) with white - on -white perimetry ( W/ WP). The correlations of the visual field indices and the point - by - point threshold between the B/YP and W/WP were analyzed. Results Of the total 42 eyes with B/YP,three (7. 14% ) showed no visual field defect, and thirty - nine eyes(92.86% ) had visual field defect. No significant correlation was found in the visual field indices mean sensitivity ( MS) , mean defect ( MD) and loss variance ( LV ) ] between B/YP and W/WP(r =0.2998 ,0.2048,0.0886, respectively). More than half of the point - by - point thresholds between B/YP and W/WP showed significant correlation. Conclusion The sensitivity of B/YP in detecting visual field defect was higher than that of W/WP. Follow - up was necessary in the patients with the location of visual field defects with B/YP in accordance with the location of the suspected visual field defect with W/WP.
