During the past decade, major eye centers around the world have used scanning laser systems from Heidelberg Engineering for their research and clinical work.

For exact data in glaucoma research the Heidelberg Retina Tomograph has become the system of choice. In more than 150 peer-reviewed papers and hundreds of abstracts, study results have confirmed unsurpassed reproducibility and consistent longitudinal data. As a result, the highest diagnostic precision to differentiate between normal eyes and early glaucomatous eyes - even before any visual field defect has been confirmed.

Three-dimensional optic nerve head topography analysis by laser scanning tomography has been shown to be superior to all other imaging technologies. Because of its advantages, this technology is now generally accepted and used to provide the best service possible for glaucoma patients and patients at risk.

Heidelberg Engineering integrated the experience from more than one million exams, advice from hundreds of users, and research data from around the world. Adding the latest available technology in electronics, optics, and software the standard glaucoma detection system of the future has been created: the Heidelberg Retina Tomograph II.

The HRTII once again marks a breakthrough product for glaucoma management from Heidelberg Engineering. This system is unique in may respects. It is the smallest scanning laser ever, light, portable and ready for telemedicine. It features automatic image acquisition, sector analysis for early glaucoma detection, and automatic progression analysis. Also, all results are presented in a format which is understood by patients to ensure their compliance.

You get maximum results for your patients and your practice for minimum outlay.
