Heidelberg Engineering Launches HRT3 to Facilitate Early Glaucoma Diagnosis; New Device Is Portable, Easy to Use and Can Analyze Glaucoma Progression.DOSSENHEIM, Germany -- Heidelberg Engineering GmbH, the leading developer of laser diagnostics for ophthalmic applications, today announced the introduction of the Heidelberg Retina Tomograph 3 (HRT HRT abbr. hormone replacement therapy Hormone replacement therapy (HRT) Also called estrogen replacement therapy, this controversial treatment is used to relieve the discomforts of menopause. 3), a newly enhanced version of its flagship product A primary product of a company, which is typically why the company was founded and/or what made it well known. For example, MS-DOS, Windows and the Microsoft Office suite have been flagship products of Microsoft. CorelDRAW is a flagship product of Corel Corporation. for the assessment, diagnosis and management of glaucoma glaucoma (glôkō`mə), ocular disorder characterized by pressure within the eyeball caused by an excessive amount of aqueous humor (the fluid substance filling the eyeball). . Like its predecessor, the HRT3 uses laser technology to produce a topographical image of a patient's optic nerve optic nerve: see vision. , providing an objective analysis of the structure's cup, rim and retinal nerve fiber layer The nerve fiber layer (or layer of nerve fibers or stratum opticum) is formed by the expansion of the fibers of the optic nerve; it is thickest near the porus opticus, gradually diminishing toward the ora serrata. . Optic disc topography has been found to be predictive of visual field loss according to a long-term study published in the April 2005 issue of the Journal of Glaucoma. Heidelberg Engineering has incorporated several new features in the HRT3 in direct response to customer feedback. These include the FastCheck(TM) Glaucoma Probability Score(TM), which is generated using an advanced form of artificial intelligence called a relevance vector machine Relevance Vector Machine (RVMs) is a machine learning technique that uses Bayesian theory to obtain sparse solutions for regression and classification. The RVM has an identical functional form to the Support Vector Machine, but provides probabilistic classification. . This sophisticated analysis provides a statistical probability of glaucoma using ethnic-specific databases. In addition, the software eliminates the need to draw contour lines or use reference planes and provides real-time feedback to assist the operator in acquiring a high-quality image. "Optic disc assessment is more important than visual field loss as the earliest indicator of glaucoma," said Dr. Gerhard Zinser, managing director and head of R&D for Heidelberg Engineering. "For more than 10 years, optometrists and ophthalmologists have been using the HRT to analyze optic discs, producing a wealth of longitudinal data. This data is confirming the role of our technology in early glaucoma detection." The HRT3 monitors the patient's condition over time, comparing baseline images with follow-up examinations and highlighting areas of statistically significant progression. Monitoring progression is important in determining the course of treatment. The HRT3 is a portable, laptop-based system that can be placed in a compact carrying case. Heidelberg Engineering expects to begin shipping the new product in the last quarter of the year.
