Relationship between automated perimetry and Heidelberg retina tomograph, optic coherence tomography and laser polarimetry in moderate to severe glaucomatous eyes

Objectives: To determine the correlations between measurements obtained with Heidelberg retina tomograph III (HRT III), optic coherence tomography (OCT), and laser polarimetry (GDx) indices of automated perimetry (AP) in moderate severe glaucoma patients. Methods: Forty-nine eyes 30 patients were included current study divided into two groups: 23 26 defined by Hodapp-Parrish-Anderson grading system. Pearson’s correlation coefficients used to evaluate AP including mean deviation (MD) pattern standard (PSD), structural parameters retinal nerve fiber layer (RNFL) disc acquired using three devices both groups. Results: In OCT GDx not correlated MD only exception inferior RNFL (r = 0.57, p 0.007 r 0.52, 0.008, respectively). Mild calculated HRT indices. glaucoma, most compared other devices. The for more powerful PSD. Parameters based on showed stronger than those head. No significant less -12 dB. Conclusions: best However, still seems be effective follow-up progression advanced glaucomatous damage.
