Abstract
- The aim of this work was to investigate the correlation between scanning laser polarimetry with variable corneal compensation (GDx VCC) parameters and blue-on-yellow perimetry (B/YP) indices in ocular hypertension (OHT). One eye each of 52 patients with OHT (with a normal visual field, a normal optic nerve, and an untreated IOP > 21 mmHg) was chosen. All patients were examined with the Octopus 101 automated perimetry dG2 program using the dynamic/normal strategy (white-on-white perimetry, W/WP), with the dG2 program using the dynamic strategy/BY method (blue-on-yellow perimetry, B/YP), and with GDx VCC. Seven of the 52 OHT patients had both B/YP visual field loss and retinal nerve fiber layer (RNFL) defects with the GDx VCC measurements, and four patients demonstrated regions of B/YP visual field defects with corresponding RNFL defects on GDx VCC examination. A mild significant correlation was found between B/YP mean sensitivity (MS) and the superior average ( R =0.138, p = 0.049). No significant correlation was found between the W/WP indices and GDx VCC parameters. B/YP MS correlated with the superior average of GDx VCC in OHT patients. The findings brought up the possibility of using both techniques for clinical examination to yield converging data. [ABSTRACT FROM AUTHOR]
