The Heildelberg 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. And 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 followup. Their long-term experience 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.

Compact & portable design

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.

Heidelberg Eye Explorer

The software of all laser-scanning and OCT* devices from Heidelberg Engineering are based on the Heidelberg Engineering are based on the Heidelberg Eye Explorer (HEYEX) operation system. The HEYEX covers all basic functions of the patient database and patient file.

Software for acquisition and analysis

Besides the full software (image acquisition and viewing) provided with each device, a separate viewing software is available for each software module, enabling users to access all image and patient data.

Participants of telemedicine-projects (shared practices etc.) which do not have an HRT in their practice can use the viewing software to import, analyze and archive data.

The HRT 3 is email-enabled to transfer patient results electronically as jpg or bmp file, making exchange of paper printouts a method of the past.

HRT 3 in network environments

HRT 3 can be used stand-alone or within network environments. For parallel use of the software on several computers within a network, additional networking licences can be obtained. These network licences cover all modules installed on the network.

Image Capture Module

The Image Capture Module enables the import of digital images or documents from other devices (fundus cameras, OCT, perimeter etc.) into the Heidelberg Eye Explorer patient file. The patient file organizes patient's images centrally, allowing for easy access, diagnosis and printing reports.

Connection to practice-management software

The HEYEX operating system can be connected to patient management software systems (IFA, Medistar, Turbomed and others). This enables quick and convenient import of patient data into the digital patient fil. Should your patient management system currently not offer connection with the HEYEX, we will be happy to make the data exchange program available to your provider free of charge for implementation. Please contact our support hotline for further information.

Glaucoma Module

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 and 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.

Retina Module

Diabetic retinopathy is the leading cause of visual impairment and blindless 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, ctstoid macular edema, occlusive diseases and macular holes. The Retina Module is the only means to precisely quantify change of retinal edema over time.

Cornea Module

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.

The HRT is one of the top predictive factors for glaucoma.

In fact, the Ocular Hypertension Treatment Study (OHTS) has shown the HRT not only identifies those patients at high risk for developing glaucoma; it can also identify those at low risk with a greater than 90% accuracy at initial assessment

• Optic disc assessment is the single most predictive factor in helping to detect glaucoma.
• Preferred practice patterns from AAO, AOA and the AIGS consensus meeting all recommend documenting the optic disc as part of routine clinical examinations.

Most glaucoma cases are first diagnosed by optic disc assessment.

In fact, OHTS has shown that HRT topographic measurements can detect structural damage up to 8 years earlier than expert assessment of stereo disc photography or visual field loss.

The HRT is the only imaging device proven by longitudinal studies to accurately measure all aspects of the optic disc: CUP, RIM, and RNFL.

• Largest normative database
• All parameters are adjusted for optic disc size
• Ethnic-selectable databases
• OU database with asymmetry analysis

You can't call it progression until you do the math.

To confidently manage the ongoing treatment of your glaucoma patients, you need to accurately track and measure the progression of their disease. Unlike other technologies that rely on simple comparison, the HRT applies statistical analysis that can help differentiate true biological change from random variability.

• Utilizes statistical progression—not simple serial comparison
• Tracks area and volume changes
