[Influence of cataract on scanning laser polarimetry].
OBJECTIVE
To evaluate the influence of cataract on scanning laser polarimetry.


METHODS
Nerve fiber layer thickness (NFLT) around the optic nerve head was measured before and after surgery in 43 eyes of 43 patients with cataract. Phacoemulsification-aspiration and intraocular lens implantation was performed in all eyes.


RESULTS
The mean NFLT increased 13.41% (p < 0.0001) postoperatively. Positive correlation(rs = 0.56, p = 0.001) was observed between NFLT measurements and cataract degree, using Lens Opacities Classification System III. Significant positive correlation(rs = 0.493, p = 0.004) was observed between NFLT measurements and posterior subcapsular cataract degree.


CONCLUSIONS
Scanning laser polarimetry may underestimate NFLT in individuals with dense cataract.
