The blue field entoptic test was applied to study macular function in 32 patients with severe ocular trauma and markedly reduced visual acuity (6/60 [20/200] or less) in whom fundus details could not be seen initially. This test is based on the entoptic phenomenon, whereby one can observe one's own leukocytes flowing in the perifoveal retinal capillaries. Twenty of the 21 patients (95%) with normal perception of the corpuscles regained a visual acuity of 6/12 (20/40) or better on follow-up, whereas ten of the 11 patients (91%) with abnormal test responses had, on follow-up, a visual acuity of counting fingers or less. The blue field entoptic test is therefore useful in prognosticating macular function in patients with reduced visual acuity due to media opacities secondary to ocular trauma.
应用蓝视标内视现象试验研究了32例严重眼外伤且视力显著下降（6/60[20/200]或更低）、最初无法看清眼底细节的患者的黄斑功能。该试验基于内视现象，即人们可以观察到自己的白细胞在黄斑周围视网膜毛细血管中流动。21例对血细胞有正常感知的患者中有20例（95%）在随访时视力恢复到6/12（20/40）或更好，而11例试验反应异常的患者中有10例（91%）在随访时视力为指数或更低。因此，蓝视标内视现象试验有助于对因眼外伤继发介质混浊而视力下降的患者的黄斑功能进行预后评估。
