Cerulean posterior capsule opacity.

We present a case of light-blue posterior capsule opacification (PCO) in a patient who had cerulean cataracts removed 1 year earlier. The color of the PCO was similar to that of the cerulean cataracts prior to extraction. Posterior capsule opacification is a common complication after cataract surgery; however, we could not find a similar case of cerulean posterior capsule opacity in the literature. The findings in this case suggest that the mechanism of the light-blue color formation in the cataract was also present in the lens epithelial cells forming the posterior capsule opacity.
