Posterior capsular opacification affects scanning laser polarimetry examination

Abstract

An artifact introduced by PCO presence can affect SLP measurements reliability.

The influence of posterior capsular opacification removal on anterior segment birefringence parameters as measured by scanning laser polarimetry

“…In our previous studies we concluded that new RNFL retardation measurements should be obtained after Nd:YAG capsulotomy to serve as a baseline for future comparisons 31,32 . The present research provides more information.…”

“…In our previous studies we concluded that new RNFL retardation measurements should be obtained after Nd:YAG capsulotomy to serve as a baseline for future comparisons. 31,32 The present research provides more information. In fact, a new eye-specific compensation of ASB is also mandatory before obtaining a new baseline of RNFL measurements because PCO removal may cause changes in CPM and CPA.…”

“…In general terms, the results of the present study coincide with our previous findings. In fact, SLP examination with GDx VCC seems to overestimate the RNFL retardation in PCO‐affected eyes 31,32 …”

Changes in Scanning Laser Polarimetry Before and After Laser Capsulotomy for Posterior Capsular Opacification

“…2,3 In contrast, we concluded that PCO removal is associated to remarkably significant changes in SLP measurements. Briefly, our results suggest that SLP examination with GDx VCC may overestimate RNFL retardation measurements in PCO-affected eyes.…”
