Application of 25 MHz B-Scan Ultrasonography to Determine the Integrity of the Posterior Capsule in Posterior Polar Cataract

Figure 1

Images of the posterior capsule (PC) under 25 MHz B-scan ultrasonography (MHzB). (a) Normal continuous PC curve (CPCC) with minimal reflectivity between the PC and posterior polar cataract (PPC) in a clinically diagnosed case of PPC. (b) Normal CPCC with high reflectivity between the PC and PPC in a clinically diagnosed case of PPC. (c) PC dehiscence with reflectivity protruding into the vitreous cavity in a clinically diagnosed case of PPC. (d) Posterior subcapsular cataract with an intact PC.
