以眼前节光学相干断层扫描(OCT)、Scheimpflug技术、高分辨率磁共振成像及裂隙扫描等为代表的眼前节影像技术提供了房角的各种参数,可测量角膜前后表面的曲率和前房内径,计算出角膜的屈光度,在准分子激光角膜原位磨镶术(LASIK)术后能够测量角膜瓣厚度,甚至可用于调节功能及老视的研究,极大地提高了诊疗水平。就几种新型眼前节影像技术的研究进展及其临床应用进行综述。
The anterior segment imaging technique, represented by anterior segment optical coherence tomography (OCT), Scheimpflug technique, high resolution magnetic resonance imaging and slit scans, provides various parameters of the angle of the anterior chamber to measure the curvature of the anterior and posterior corneal surfaces and the anterior chamber Diameter, calculate the corneal refractive power, corneal flap thickness can be measured after laser in situ keratomileusis (LASIK) surgery, and even can be used for regulatory function and presbyopia research, greatly improving the level of diagnosis and treatment. The research progress and clinical application of several new anterior segment imaging techniques are reviewed.
