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