Optical coherence tomography (OCT) is a non-invasive, high-resolution imaging modality to acquire cross-sections and three-dimensional images of the microstructure in biological specimens. Because of rapid improvement of acquisition speed and axial resolution of OCT over recent years, OCT is becoming increasingly used in clinic for diagnosing or analyzing diseases of the eye, especially in the fundus. However, OCT has been used regardless of the location of lesions and the clarity of optical media. This misuse wastes resources and delays diagnosis and treatment of certain ocular diseases. Furthermore, the image of SD-OCT cannot be analyzed completely at present. Therefore, how to apply OCT in clinic appropriately and to analyze its image professionally is crucial, which should attract the attention of ophthalmologists. In addition, comprehensively analyzing ocular diseases combined with other examinations is extremely important to improve the level of diagnosis.
光学相干断层扫描（OCT）是一种非侵入性的高分辨率成像方式，用于获取生物标本微观结构的横截面和三维图像。由于近年来OCT采集速度和轴向分辨率的快速提高，OCT在临床上越来越多地用于诊断或分析眼部疾病，尤其是眼底疾病。然而，OCT的使用并未考虑病变的位置和光学介质的清晰度。这种不当使用浪费了资源，并延误了某些眼部疾病的诊断和治疗。此外，目前还无法对谱域OCT（SD-OCT）图像进行全面分析。因此，如何在临床上合理应用OCT并对其图像进行专业分析至关重要，这应引起眼科医生的关注。此外，结合其他检查综合分析眼部疾病对于提高诊断水平极为重要。
