Application of 14-MHz Ultrasonography with Tissue Harmonic Imaging to Determine Posterior Capsule Integrity in Traumatic Cataract

Figure 3

False-positive image of PC by 14 MHz + THI. (a) The shape of the lens is regular, the internal echo is uniform, and the PC echo is regular. A moderate echo band is shown and was mistaken for a passage (long arrow). (b) The shape of the lens is not regular, the internal echo is not uniform, the anterior capsule is ruptured, and the PC of the equator shows a sharp echo, which was mistaken for rupture (short arrow).
