OCT Biometry (B-OCT): A New Method for Measuring Ocular Axial Dimensions

Figure 3

Lens opacity location in B-OCT (REVO NX) and its effect on the visibility of the posterior retinal boundary. (a, b) Opacity of the anterior part of the lens and nucleus; (c) increased lens reflexivity corresponding to nuclear cataract; (d) nuclear and posterior subcortical opacity. Despite significant retinal shading, the posterior retinal boundary remains visible and is accurately identified; (e–g) posterior subcapsular opacity of increasing density degree. A thick subcapsular opacity in (g) cast a major shade on the sensory retina. However, the posterior boundary of the retina was imaged. The red arrows indicate retinal shading due to lens opacity.
