چکیده
PURPOSE To determine the correlations between optic nerve head (ONH) parameters measured with the Heidelberg Retina Tomograph (HRT), and the main outcomes of standard automated perimetry (SAP) in normal, ocular hypertensive, glaucoma suspects and glaucomatous subjects. METHODS Four hundred and twenty-three patients were enrolled in the study and classified into four groups depending on baseline intraocular pressure, optic nerve head morphology, and SAP results: 87 normal eyes, 192 ocular hypertensive eyes, 70 glaucoma suspects and 74 glaucomatous eyes. In the different diagnostic groups, Pearson's correlation coefficients were calculated between ONH parameters and mean deviation, pattern standard deviation (PSD), number of altered points in each quadrant of the visual field (superior-nasal, inferior-nasal, superior-temporal and inferior-temporal), number of points altered at different probability levels, and threshold values at each point of SAP. RESULTS In the normal and ocular hypertensive groups, only a few weak correlations were found between HRT and SAP parameters. The strength and number of significant correlations increased in the suspected glaucoma group. The glaucoma group had the strongest correlations, particularly between cup/disc ratio and rim/disc ratio with MD (r=0.479) and between rim area and PSD (r=0.444). CONCLUSIONS Weak to moderate correlations were found between some ONH parameters obtained with the HRT and SAP results in the glaucoma group.

Comparison between Optic Nerve Head Topography – Using the Heidelberg Retina Tomograph – and Resolution Visual Fields
Early diagnosis is probably essential for the outcome of glaucoma treatment, and a number of methods for detecting glaucomatous damage have been developed and evaluated1. Resolution perimetry (HRP)2,3, measuring spatial resolution, is one of the methods with the highest sensitivity1. It has been found to be reliable and useful in the management and follow-up of glaucoma4-10. Another way of dete...

In this paper a new non-linear multivariable regression method is presented to investigate the existence of correlation between the central corneal thickness (CCT) and the optic nerve head (ONH) topographic measurements in patients with glaucoma. Specifically, the model is supplied with Heidelberg Retina Tomograph II data including optic nerve head topographic parameters (i.e. disc area, etc) a...
