Heidelberg Retina Tomography – HRT 3:

HRT3 is a confocal laser scanning system, designed to capture and analyze three-dimensional images of the posterior segment of the eye. It allows a quantitative assessment of the topography in the structures of the eye, especially of the retinal topography, as well as the precise tracking of any topographical changes. It is applied more often to describe the glaucomatous optic nerve head, the analysis of the slits and the edema of the macula and the analysis of imperfections in the layer of the nerve fibers.
