[Diagnosis and follow-up in glaucoma patients using the Heidelberg retina tomograph]

The development of laser scanning tomography in the late 1980s enabled the possibility of an exact three-dimensional biomorphorphometry of the optic nerve head. This technique is designed for 3D measurement of the topography of the optic disc with high accuracy and reproducibility. With the development of the Heidelberg retina tomograph with highly advanced and user-friendly software, a quick examination is possible. Currently the instrument is already used on a routine basis in the ophthalmological practice. It has been shown that glaucomatous changes of the optic disc can be detected using laser scanning tomography before perimetric deterioration occurs. Therefore this technique is crucial in the follow-up of glaucoma patients.
