Figure 7
En face scleral PD-OCT images of the eye in Fig. 4. Polarization-independent OCT images (a–d) and polarization-dependent OCT images (e–h). PD-OCT B-scan images (a, e) were flattened with respect to Bruch’s membrane (green lines) to generate a reference plane (red lines) for en face scleral images (b, f). En face scleral image of polarization-independent OCT (b) shows real scleral vessels (white arrows) in the shadows of choroidal structures. Black lines indicate five sets of macular scan lines. White line indicates the upper scan line (c, g) and red line indicates lower scan line (d, h). En face scleral image of polarization-dependent OCT image (f) shows the distribution of artifactual low-intensity areas. By comparison with polarization-independent OCT B-scan images in upper (c) and lower (d) scan lines, scleral vessel artifacts in polarization-dependent OCT B-scan images are identified in both upper (g) and lower (h) scan lines (red arrows).
