Purpose Of Review:
To summarize the literature on three-dimensional (3D) technological advances in ophthalmology, the quantitative methods associated with this, and their improved ability to help detect glaucoma disease progression.
Recent Findings:
Improvements in measuring glaucomatous structural changes are the result of dual innovations in optical coherence tomography (OCT) imaging technology and in associated quantitative software.
Summary:
Compared with two-dimensional (2D) OCT parameters, newer 3D parameters provide more data and fewer artifacts.
