Posterior capsular opacification affects scanning laser polarimetry examination.
OBJECTIVE
To illustrate the effect of posterior capsular opacification (PCO) on retinal nerve fiber layer (RNFL) retardation measurements obtained during scanning laser polarimetry (SLP).


METHODS
SLP was performed using GDx VCC on three eyes of three non-glaucomatous patients with clinically significant PCO, before and after Nd:YAG capsulotomy.


RESULTS
PCO removal by Nd:YAG capsulotomy was associated with marked variations in retardation map morphology and with apparent RNFL thinning. Retardation map atypia decreased and typical scan score (TSS) increased remarkably after capsulotomy in all three cases.


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