[Analysis of the nerve fiber layer using GDx in pseudophakic patients with posterior capsular opacification].

Purpose: To evaluate if posterior capsule opacification (PCO) would alter the analysis of nerve fiber layer using the scanning laser polarimetry (GDx).

Methods: Pseudophakic non-glaucomatosous eyes (37 patients) underwent nerve fiber layer analysis using GDx before and after posterior capsulotomy with Nd:YAG Laser.

Results: In five eyes, GDx did not obtain acceptable images using the device's parameters of acquisition.

[Retinal nerve fiber layer alteration in chronic users of chloroquine].

Purposes: To evaluate the retina nerve fiber layer by laser polarimetry in patients in chronic use of chloroquine.

Methods: Forty-four eyes of twenty-two patients were studied. These were in use of chloroquine due to rheumatic diseases during at least one year.
