Abstract

Abstract: : Purpose: To evaluate the sectorial correlation between Heidelberg Retina Tomograph (HRT) parameters and the Frequency Doubling Technology (FDT) indices. Methods: One eye was randomly chosen from 100 patients with primary open angle glaucoma (abnormal visual field and/or abnormal optic nerve and untreated IOP above 21 mmHg) and ocular hypertension (normal visual field and normal optic nerve and untreated IOP above 21mmHg). All the patients were examined with Humphrey Perimeter program 24–2, SITA standard, FDT program C 20–5 and HRT. Findings were analysed using Pearson's correlation coefficient and linear regression model. Results: Significant (P<0.001) correlation was found between FDT mean deviation and rim area (RA) (r=0.43) and cup shape measure (CSM) (r=–0.34) and between FDT pattern standard deviation and RA (r=–0.44) and CSM (r=0.27). Significant (P<0.001) sectorial correlation was found between FDT sensitivity and RA and CSM. When a linear regression model was applied, RA was the most predictor parameter of FDT. Conclusions: In this glaucomatous group cup shape measure and rim area were significantly correlated to FDT indices. Rim area showed to be more predictive of FDT sensitivity than CSM.
