HRT3 - Heidelberg Retina Tomograph

The Heidelberg Retina Tomograph 3 (HRT 3) is a confocal laser scanning system for imaging of the anterior and posterior segments of the eye. It comprises three modules which can be used independently or combined with each other. The major routine clinical application is analysis of the optic nerve head structure for glaucoma diagnosis. A second application is in diabetes for the location and quantification of retinal edema. With the Rostock Cornea Module, the HRT 3 is converted into a confocal microscope for in vivo assessment of the cornea and conjunctiva.

Worldwide, more than 5.000 HRTs support physicians and optometrists in diagnosis and follow-up. Their experience over time has confirmed the high diagnostic value of HRT examinations, based on highly reproducible measurements. Both 2- and 3-dimensional images are acquired with high resolution and without data interpolation. Built-in quality controls enable the user to evaluate image quality during and after the acquisition. The HRT is a tried-and-tested, versatile technology you can rely on.

The new compact HRT 3 platform is ideal for different practice environments as well as shared use. The HRT 3 is now notebook or PC enabled, using the latest FireWire technology. A new ergonomically designed notebook table offers an elegant look, but also convenient access for both physician and patient, including those in wheelchairs. Alternatively, the HRT 3 can be used with a standard PC and table. An optional carrying case slides over the scanning head, enabling easy and secure transportation between offices.

The new HRT 3 is the single most powerful technology to help you assess, diagnose and manage glaucoma. The new Glaucoma Probability Score (GPS) gives an objective, user-independent, structural assessment of the optic nerve head using artificial intelligence and ethnic-specific databases. Enhanced progression analyses identify and track areas of statistically significant change over time to assess glaucomatous progression. These tools increase physician confidence in detecting real, clinically significant changes in optic nerve head structure.

Diabetic retinopathy is the leading cause of visual impairment and blindness in the western adult population. The Retina Module automatically locates and quantifies edema. Physicians appreciate this quick and noninvasive method to assess diabetic macular edema, central serous retinopathy, cystoid
macular edema, occlusive diseases and macular holes. The Retina Module is the only means to precisely quantify change of retinal edema over time.

In vivo imaging of cornea, limbus and conjunctiva can be made. One micron resolution gives high definition analysis and superb detail of corneal structures in real
time and the ability to evaluate and monitor corneal pathology, pre- and post-op. LASIK, keratoplasty or corneal health of contact lens wearers. In addition, endothelial cell counting as well as intra-corneal pachymetry can be performed.
