Abstract
Embodiments of OCT measurement and analysis techniques described herein enable precise 3D anterior chamber angle measurement from major, pertinent landmarks in the eye. Such techniques result in a more reliable, quantifiable angle measurement technique that is both non-invasive and non-contact in nature, thereby improving clinical practicality, while improving patient comfort and care. For example, a method is provided for in vivo imaging of an eye, including taking a plurality of optical coherence tomography (OCT) line scans of an eye to obtain a 3-dimensional (3D) radial scan pattern, the individual line scans including a plurality of axial scans, and obtaining a three-dimensional image of an anterior chamber angle of the eye from the radial scan pattern.
