CLINICAL CASES
Three eyes with central retinal artery occlusion (CRAO) have been studied. Optical coherence tomography (OCT) was performed in each of them. Ophthalmoscopic signs of CRAO were equivocal in the three eyes. However, the presence of a hyporeflective signal in the OCT scan could be seen clearly in each of them.
DISCUSSION
The presence of a hyporeflective band between the neurosensory retina and the retinal pigment epithelium in OCT images, that persist for several months after a CRAO episode, is useful in establishing the diagnosis in these patients.
临床病例
对三只患有视网膜中央动脉阻塞（CRAO）的眼睛进行了研究。每只眼睛均进行了光学相干断层扫描（OCT）。这三只眼睛的CRAO检眼镜体征不明确。然而，在每只眼睛的OCT扫描中都能清楚地看到低反射信号的存在。
讨论
在OCT图像中，神经感觉视网膜和视网膜色素上皮之间存在低反射带，在CRAO发作后持续数月，这有助于对这些患者进行诊断。
