HEIDELBERG RETINAL TOMOGRAPHY

The Heidelberg Retina Tomograph (HRT) is a laser light that scans the retina and other areas of the eye. Starting above the retinal surface, then capturing parallel images at increasing depths. The stacks of images can be combined to create three-dimensional images of the optic nerve and the retinal nerve fibres. Images are aligned and compared for both individual examinations and for detecting progression between examinations

PROCEDURE

For the HRT, you will be seated in a chair in the diagnostic procedure room. Your head will then be positioned so that your chin is resting in front of the HRT machine. During the test, a technician will have you look in certain directions, and you may see several lights. The test is completely painless and safe, the entire procedure takes only a few minutes.
