摘　　要：目的应用光学相干断层成像（ＯＣＴ）技术对正常眼黄斑区视网膜神经上皮层厚度进行测定。方法对３０只经眼科检查确认的正常眼按同一方法进行黄斑区图像采集，并使用随机软件对其神经上皮层厚度进行测量。将所得数据按距中心点距离和方位进行分类统计计算和检验。结果显著性检验证明测量所得 １３２０个数据具有良好的可信性，且结果与以往类似报道相符。结论ＯＣＴ能够对视网膜神经上皮层厚度进行精确的量化测定，正常值测定的结果有助于对眼底疾病的理解。Objective To measure the thickness of the neurosensory retina of macula by optical coherence tomography (OCT) in normal eyes to get criterion for clinical practice. Methods 30 normal eyes validated by routine ophthalmic examination were scanned and measured by OCT using the same method. 4 scan lines traversing the fovea with the same length and the same angle gap. The thickness of the neurosensory retina on given spots were measured and noted. Results 1320 data were collected and grouped according to the distance and directions to the central. Significant test showed that the reproducibility of this process was good. All these results were consonant with the previous reports. Conclusion OCT appears potentially useful for quantitatively characterizing the thickness of the neurosensory retina of macula. The tomographic information provided by OCT eventually may lead to a better understanding of the pathogensis of ocular fudus diseases.
