As such, their loss in imaging protocols, algorithms, and new parameters that have enhanced this area is, at least potentially, more readily detectable than the its utility for the diagnosis and assessment of glaucoma progression. loss of pRNFL. In this review, we examine the clinical utility of OCT in the diagnosis Spectral-domain OCT is rapidly evolving, offering faster of glaucoma and monitoring of its progression, and emphasize the scanning speed, 3-dimensional (3D) image acquisition patterns technological advances that facilitate both glaucoma research and the as well as reproducible registration and advanced segmentation formulation of clinical management strategies. algorithms. Such SD-OCT instruments are commercially available from a number of manufacturers.
