Henson 9000 Perimeter presents a vision for advancing visual field testing through innovation, operator efficiency, and patient comfort. It traces the impact of early computerized perimeter technology, including standardized printouts and electronic result storage, then highlights newer adaptive test approaches such as Smart Supra and ZATA. The document emphasizes faster, more manageable testing, improved sensitivity for central defects, progression analysis tools, and flexible options to re-test, add, or extend locations without restarting.

Henson 9000 Henson Leading the field Optimized perimetry for practitioners and patients THE HENSON STORY Over 30 years of innovation The Henson brand is driven by three clear principles: innovation, improving operator efficiency and ensuring patient comfort. These have motivated us since the launch of our first screener in 1986 and continue to do so to this day with the Henson 9000 Perimeter. When Professor Henson invented the CFS 2000 it was the world’s first computerized, multiple-stimulus, supra-threshold perimeter. Its release revolutionized the way in which visual field tests were performed. It produced a standard printout and allowed the electronic storage of results for future recall or transfer to other computers. By introducing the concept of extending tests the CFS 2000 also made life easier for patients, by shortening tests for those who were at low risk of glaucoma, thereby speeding up practice workflow, too. Our desire to constantly improve our products is driven both by Professor Henson’s expertise as a respected academic and his close understanding of practitioner needs, first from his time as a practicing optometrist and then as a clinical academic at Cardiff University, Manchester University and Manchester Royal Eye Hospital. This has also allowed the Henson range to claim some notable firsts. In 1993 the Henson CFA 4000 became the first perimeter to allow operators to retest and/ or add points during a visual field test for improved specificity. In 2009, ZATA was the first threshold test to use prior test data for threshold tests, reducing test times and making tests more manageable for patients. To improve sensitivity to small central defects, often missed by 24-2 tests1, the Smart Supra test allows the operator to include an additional 32 test locations in the central 10 degrees. This 86 point test can be completed in ~3.5 minutes.* In addition, the Smart Supra test uses supra-threshold increments based upon probability limits, thus providing pattern and total deviation probability map outputs similar to those seen in threshold tests. Today, the Henson 9000 is the first choice of UK optometrists and has a growing install base within optometry and ophthalmology worldwide. Professor David Henson: innovating in the field of perimetry since 1986. When you choose Henson you choose ground-breaking innovation that will benefit you and your patients. *Test times are approximations only and will differ according to patient response time and level of loss. Henson 9000 With innovative tests for detecting and monitoring changes to visual fields, a full suite of analytical tools (including progression analysis), networking capabilities and a compact, modern, low maintenance design, the Henson 9000 offers a lot to practitioners. HENSON 9000 PERIMETER All you would expect from your field analyzer, and more Our commitment to innovation ensures that we can respond to the latest research to provide a perimeter that always benefits you and your patients. Smart Supra Smart Supra was uniquely developed in response to recent research which showed that 24-2 test patterns missa large number of early field defects.1 Smart Supra can be extended beyond its 24-2 pattern with an additional 32 test locations in the central 10 degrees in a 3.5 minute test. Its standard 26 point screening test can be completed in less than one minute.* ZATA Our intelligent alternative to SITA, ZATA can start a threshold test from prior patient data. It uses smart threshold-related terminating criteria to optimize test performance and includes powerful tools for analyzing progression. Tests (24-2) can typically be completed in as little as 2.5 minutes per eye,* providing clear benefits to operator and patient alike. 4 *Test times are approximations only and will differ according to patient response time and level of loss.

FAQs

What principles drive the Henson 9000 brand?

The document states three clear principles: innovation, improving operator efficiency, and ensuring patient comfort.

How does Smart Supra improve detection in visual field testing?

Smart Supra extends beyond a 24-2 pattern by adding 32 test locations in the central 10 degrees, aiming to improve sensitivity to small central defects.

What is ZATA and what benefit does it provide?

ZATA is described as an intelligent alternative that starts threshold tests using prior patient data and uses terminating criteria to optimize performance, also supporting tools for analyzing progression.
