We read with interest what the authors have beautifully described as “sinking cortex sign” for the pre-existing posterior capsular defect.[1] We also observed a case having central lucency in diffuse illumination [Figure 1]a in the area of the sinking cortex visible in slit illumination [Figure 1]b because of localized lens volume loss. We would like to add that the gold standard for diagnosis we believe will always be ultrasound biomicroscopy (UBM) [Figure 1]c, which is superior to ultrasound B-scan as described by authors. We can literally visualize the “sinking cortex” on UBM.
