摘要相干光断层成像(OCT)是一种非侵入性,高分辨率的成像技术,可以获取生物组织超微结构的横截面及三维图像.随着近年来OCT检测技术的不断改进,其成像速度加快,分辨率提高,因此被广泛应用于眼科临床,尤其在眼底疾病的辅助诊断方面显示出明显的优势.但也有部分眼科医师对OCT检测的适应证掌握不严,在尚未了解患者病变部位及屈光间质是否清晰的情况下,均行OCT检查.这样不但浪费医疗资源,增加患者经济负担,甚至贻误疾病诊断.随着频域OCT检测技术的快速发展,解读OCT图像的难度也相应增加,因此需要眼科医师不断提高科学解读OCT图像的水平和能力,从而综合分析和判断患者病情.合理选择OCT检测的适应证、科学解读OCT图像是临床确诊的重要前提,应引起临床眼科工作者的高度重视.

abstractsOptical 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.
