“…Several research works into the effect that PCO and subsequent Nd:YAG capsulotomy have on the SLP results of RNFL retardation measurements have been conducted [ 22 – 26 ]. With this purpose in mind, our research group performed a study into PCO-affected eyes and SLP, selected using GDx VCC, on each patient before and after capsulotomy.…”

“…Vetrugno et al [ 24 ] reported modifications in symmetry, inferior ratio, superior, nasal, and temporal-superior-nasal-inferior-temporal SD whereas Brittain et al [ 25 ] showed significant changes in the typical scan score and temporal-superior-nasal-inferior-temporal average. In addition, Arraes et al did not show any significant difference between the thickness parameters before and after posterior capsulotomy in patients with moderate degrees of PCO [ 26 ]. The variability of the results can be related to the fact that anterior segment birefringence is only assessed before and after laser capsulotomy [ 23 ] or only before capsulotomy [ 25 ].…”

The visual outcome obtained after cataract removal may progressively decline because of posterior capsular opacification (PCO). This condition can be treated by creating an opening in the posterior lens capsule by Nd:YAG laser capsulotomy. PCO optical imperfections cause several light reflection, refraction, and diffraction phenomena, which may interfere with the functional and structural tests performed in different ocular locations for the diagnosis and follow-up of ocular disease, like macular and optic nerve diseases. Some parameters measured by visual field examinations, scanning laser polarimetry, and optical coherence tomography (OCT) have changed after PCO removal. Imaging quality also changes following capsulotomy. Consequently, the results of ancillary tests in pseudophakic eyes for studying ocular diseases like glaucoma or maculopathies should be correlated with other clinical examinations, for example, slit-lamp biomicroscopy or funduscopy. If PCO is clinically significant, a new baseline should be set for future comparisons following capsulotomy when using automated perimetry and scanning laser polarimetry. To perform OCT in the presence of PCO, reliable examinations (considering signal strength) apparently guarantee that measurements are not influenced by PCO.

Early diagnosis of glaucoma requires evaluation of the retinal nerve fiber layer (RNFL) to pick-up subtle changes before visual field defects. Scanning laser polarimetry using the GDx VCC offers a unique tool for imaging of RNFL changes in glaucoma. It is useful for early diagnosis and also to detect progression of glaucoma. The following review covers the basic principles, interpretation, clinical utility of this technology and reviews the literature on its current applications.
