Bringing the visual field analysis to the next level Automated Tracked Perimetry overcomes limitations in visual field testing when compared to Standard Automated Perimetry (SAP). iCare COMPASS® is an automated perimeter combined with an active retinal tracker and a scanning ophthalmoscope. This advanced technology provides retinal sensitivity and fixation analysis, as well as TrueColor Confocal imaging of the retina.
The new features Smart Progression Analysis report and SmartMosaic function can provide more information on the changes of the visual field and the condition of the retinal structure.
Automated Tracked Perimetry is a technique that images the retina during visual field testing, enabling a reliable correlation to be made between visual function and retinal structure. Retinal tracking is at the heart of this function.
Automated, continuous tracking of eye movements by infrared scanning of the retina provides active compensation for fixation losses. The perimetric stimuli automatically reposition prior to and during projection based on the current eye position. This ensures an accurate match between function (i.e. retinal sensitivity values) and structure (fundus image) thanks to the compensation for eye movements that results in the reduction of motion artifacts.
As a perimeter, iCare COMPASS offers full compatibility with standard 24-2, 30-2 and 10-2 visual field testing containing age-matched databases of retinal sensitivity in normal subjects. For the first time in a visual field test, iCare COMPASS provides 60° confocal images of the retina in TrueColor, Infrared and Red-free. iCare COMPASS is also the first perimeter to provide high resolution stereo viewing for a better assessment of the optic nerve head.
The case studies are available for download in convenient product category packages.
The ZEST Fast strategy significantly reduces exam time while providing comparable results to the ZEST strategy. The new study published in Journal of Glaucoma shows that the exam time was reduced 31% in glaucoma patients and 38 % in patients without glaucoma. Reducing test time without compromising accuracy is of paramount importance for clinical practice, since a shorter test can increase patient comfort and, as many studies demonstrated, perimetric sensitivity and variability is affected by increased examination duration.
iCare COMPASS is the first perimeter that can perform standard visual field tests, while delivering ultra-high resolution confocal TrueColor fundus images simultaneously.
With the iCare COMPASS Automatic Refraction Correction, the Auto-focus, there is no need for trial lenses. This not only reduces the examination time but avoids lens rim artefacts and improves patient flow and comfort. The test can be suspended at any time without data loss. The touch screen interface via high resolution integrated tablet and the all-in-one design (no external PC) with 1 Ethernet and 3 USB Ports make the device easy to operate. iCare COMPASS also offers embedded capabilities for network connectivity that allows remote viewing and storing data on a remote shared folder.
