Guided Progression Analysis (GPA) is a function of HFA3

It allows the detection and assessment of changes in glaucoma progression using mixed SITA tests taken on any HFA instrument.

Informing your decision-making with GPA

Informing your decision-making with GPA

Is your patient recovering, stable, or getting worse? Check with GPA to find the answer. GPA helps you to prioritize or augment glaucoma treatment by assessing the probability of visual field impairment.

GPA adds value to your practice

Guided Progression Analysis (GPA) provides an overview of the patient’s entire visual field history, streamlines workflow and can improve clinical confidence. GPA simplifies and standardizes analysis of changes in glaucomatous visual fields. It highlights any changes from baseline that represent larger than expected clinical variability and provides plain-language messages whenever changes show consistent and statistically significant loss.

Visual Field Index™ (VFI™> ) Trend is a regression analysis of the VFI values. It plots visual field loss against the patients' age, as well as rate of progression.
Glaucoma Change Probability Map is designed to identify progression events in consecutive visits at individual test points.
GPA Alert displays a plan language message about the likelihood of disease progression.

If the (GPA) slope is steep, it gives a projection and tells me what I need to be doing. And it also helps me if we need to advance therapy and create a greater burden on the patient. I can show them their glaucoma. They see it. They understand it.

Leveraging GPA for Glaucoma Management and Improved Outcomes

April Jasper, OD and Robert Fechtner, MD discuss Do’s, Don’ts and How-to's in a 12-minute conversation packed with tips, visuals and clinical examples proving that GPA is an easy to use and powerful “early warning“ system for glaucoma doctors and patients.

Minimize time. Maximize information with 24-2C.

Reduce testing time by up to 50% with SITA Faster 24-2 threshold testing. The SITA Faster 24-2C test adds ten additional points for the central visual field. And the points selected cover the areas that are known to be susceptible to glaucomatous defects.

Threshold testing is faster than ever with SITA Faster 24-2

SITA Faster 24-2 improves clinical workflow and patient satisfaction with the fastest test time in HFA threshold testing. Approximately 50% faster than SITA Standard, SITA Faster 24-2 is also about 30% quicker than SITA Fast, yet offers the same reproducibility.

Tracking rate of progression more often in less time with SITA Faster

Prof. Anders Heijl, one of the inventors of SITA algorithms and a pioneer of computerized perimetry, explains why SITA Faster is on its way to becoming the new gold standard in visual field testing.

…the accuracy of the precision of SITA Faster should be the same as with SITA Fast… we consider the data between SITA Fast and SITA Faster to be completely interchangeable

New SITA Faster 24-2C adds ten test points to the 24-2 pattern, which were selected to examine areas along physiologically relevant nerve fiber bundles known to be susceptible to glaucomatous defects.

SITA Faster with 24-2C: A winning combination

Dr. C. Gustavo De Moraes, an expert in structural and functional changes in glaucoma, explains how the SITA Faster 24-2C testing paradigm helps detecting early macular involvement in the central field defects and how this new test can help elevating glaucoma practice.

There is compelling evidence that even in early glaucoma cases, the macula may be affected, but you need to use an adequate test to make sure that damage is real.

The Evolution of Perimetry

As the engine driving ZEISS HFA, SITA has come a long way since it was first developed for Humphrey Field Analyzer. Today, the innovation first designed to optimize visual field testing is doing that and much more, for both doctors and patients. This video documentary narrated by the creators of the SITA algorithm, Prof. Anders Heijl and Prof. Boel Bengtsson, goes over the rich history and the current ambition of the ever evolving SITA.
