New developments in optical coherence tomography imaging for glaucoma

Purpose of review Since its introduction in ophthalmology, optical coherence tomography (OCT) has undergone significant advances in imaging protocols, algorithms, and addition of new parameters which have maximized its potential for diagnosing, evaluating the response to treatment, and assessing the progression of various ocular diseases, including glaucoma. This review provides an update on recent developments in OCT with respect to the management of glaucoma. Recent findings Most recent notable developments include the introduction of the minimum distance band, which is a three-dimensional optic nerve head parameter, and Swept-Source OCT with its single wide-field scanning capability. The introduction of OCT angiography provides additional structural and functional measures for glaucoma management. Adaptive optics helps visualize individual RNFL bundles and measure their widths. Summary Continued improvements in OCT technology is both enhancing our understanding of glaucoma and improving our ability to manage the disease.
