Anterior Chamber Angle Evaluation with Fourier-Domain Optical Coherence Tomography
Figure 1
Two scans of the same nasal angle in a normal subject. (a) Fourier-domain RTVue OCT image using a 6 mm CL-Angle scan pattern. Schwalbe’s line (SL), trabecular meshwork (TM), Schlemm’s canal (SC), and scleral spur (SS) are visible. However, the iris root (IR) and angle recess (AR) are not visible in this image. (b) Time-domain Visante OCT image using a 10 mm high-resolution corneal scan pattern. In this image, both the scleral spur and angle recess are visible, but the trabecular meshwork, Schlemm’s canal, and Schwalbe’s line are not resolvable.
