The blue field entoptic phenomenon (BFE), which allows the observation of one's own leukocytes flowing in macular retinal capillaries, was used to predict postoperative macular function in 136 consecutive patients undergoing uncomplicated cataract operation. The results were compared to those obtained with three commonly used tests: two-light discrimination, color perception, and the Purkinje vascular entoptic phenomenon. All four tests identified a nearly equal number of the good maculae (visual acuity 20/40 of better) ranging from 87% for the two-light discrimination test to 94% for the BFE test. However, the tests varied greatly in predicting poor macular function (visual acuity 20/50 or worse). The BFE test identified more than 75% of the poor maculae; the Purkinje vascular entoptic test and the two-light discrimination test, only 22%; and the color perception test, 11%. A positive response to the BFE test indicated a .98 probability of good macular function; a negative response indicated a .82 probability of poor macular function, predictions that were better than the other three tests or their combination.
蓝视标内视现象（BFE）可用于观察自身白细胞在黄斑视网膜毛细血管中的流动情况，我们利用该现象对136例接受单纯白内障手术的连续患者的术后黄斑功能进行了预测。将结果与通过三项常用测试获得的结果进行了比较：两点辨别、颜色感知和浦肯野血管内视现象。所有四项测试识别出的黄斑功能良好（视力20/40及以上）的患者数量几乎相同，两点辨别测试为87%，BFE测试为94%。然而，在预测黄斑功能差（视力20/50及以下）方面，这些测试差异很大。BFE测试识别出超过75%的黄斑功能差的患者；浦肯野血管内视测试和两点辨别测试仅为22%；颜色感知测试为11%。BFE测试呈阳性反应表明黄斑功能良好的概率为0.98；呈阴性反应表明黄斑功能差的概率为0.82，这些预测比其他三项测试或它们的组合更好。
