The technology of optical coherence tomography (OCT) has evolved rapidly from time-domain to spectral-domain and swept-source OCT over the recent years. OCT has become an important tool for assessment of the anterior chamber angle and detection of angle closure. Improvement in image resolution and scan speed of OCT has facilitated a more detailed and comprehensive analysis of the anterior chamber angle. It is now possible to examine Schwalbe's line and Schlemm's canal along with the scleral spur. High-speed imaging allows evaluation of the angle in 360°. With three-dimensional reconstruction, visualization of the iris profiles and the angle configurations is enhanced. This article summarizes the development and application of OCT for anterior chamber angle measurement, detection of angle closure, and investigation of the pathophysiology of primary angle closure.
近年来，光学相干断层扫描（OCT）技术从时域发展到了频域和扫频源 OCT，发展迅速。OCT 已成为评估前房角和检测房角关闭的重要工具。OCT 图像分辨率和扫描速度的提高促进了前房角的更详细和全面的分析。现在可以检查施瓦贝线和施累姆氏管以及巩膜突。高速成像允许以 360°评估角度。通过三维重建，可以增强虹膜轮廓和角度结构的可视化。本文总结了 OCT 在测量前房角、检测房角关闭以及研究原发性房角关闭的病理生理学方面的发展和应用。
