HRT+HEP – The perfect couple for a reliable glaucoma diagnosis

April 28, 2010

Heidelberg Engineering is a high-tech medical device company which designs, manufactures, and distributes diagnostic instruments for eye care professionals. It is a privately held company, headquartered in Heidelberg, Germany.

Heidelberg Engineering complements the gold standard of structural glaucoma diagnosis, the Heidelberg Retina Tomograph (HRT) with an innovative and reliable partner, the Heidelberg Edge Perimeter (HEP).

The HRT is a confocal laser scanning ophthalmoscope designed for the examination of the eye’s posterior pole. The integrated Moorfields Regression Analysis (MRA) classifies the optic nerve head (ONH) into healthy or glaucomatous by detecting diffuse and focal changes of the neuroretinal rim area.

Evaluating the central visual field, the HEP is designed for the use in early glaucoma detection as well as in progression analysis. The multi-functional HEP uses two different stimuli in one perimeter: the unique Flicker-Defined-Form (FDF) stimulus that creates an illusory “edge” contour and the well-known Standard Automated white-on-white Perimetry (SAP), that is useful in patients with moderate to severe disease and for continuity of care.

The new approach of HEP to visual fields was designed to work in combination with the well-established HRT. The Structure-Function Map (SF Map), a single report, is a combination of the HRT’s ability to classify significant change of the ONH and conjointly displays the given structural information with the functional information of the visual field.
