Discriminating Between Normal and Glaucomatous Eyes Using the Heidelberg Retina Tomograph, GDx Nerve Fiber Analyzer, and Optical Coherence Tomograph

Abstract

NEW METHODS including confocal scanning laser ophthalmoscopy, scanning laser polarimetry, and optical coherence tomography have been developed to provide real-time, quantitative information describing the optic disc and retinal nerve fiber layer (RNFL). Each of these methods uses different features of the retina or RNFL, and different properties of light to obtain clinical measurements of optic disc topography or RNFL thickness. Because RNFL and optic disc damage have been shown to precede visual field loss,^1-8 objective methods of measuring these conditions may help physicians diagnose and monitor glaucoma.
