Anterior Chamber Angle Evaluation with Fourier-Domain Optical Coherence Tomography
Figure 5
Pre- and postlaser peripheral iridotomy OCT images of an eye with narrow angles. (a) Preoperative image of the nasal angle with frame averaging. The short distance between the trabecular meshwork (TM) and the iris indicates a narrow, potentially occluded angle. The AOD-SL (dotted line) measured 120 μm. An aqueous collector vein and the Schlemm’s canal (SC) are also visible. (b) Frame-averaged cross-sectional OCT image of the same angle following laser peripheral iridotomy. The procedure nearly doubled the AOD-SL (dotted line) to 220 μm, reprinted with permission from SLACK Incorporated: Huang D, Duker JS, Fujimoto JG, Lumbroso B, Schuman JS, Weinreb RN.
