The advantage of Fundus-controlled Perimetry

Fundus-controlled 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.

Continuous and-, automated, tracking of eye movements by infrared scanning of the retina provides active compensation for fixation losses. The perimetric stimuli is automatically repositioned 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.

Simultaneous visual field tests and high-resolution TrueColor fundus images

iCare COMPASS is the first fundus-controlled perimeter that can perform standard visual field tests, while delivering ultra-high resolution confocal TrueColor fundus images simultaneously.

Easy-to-use, patient-friendly, and efficient perimetry

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.

Clinical case with iCare COMPASS

In January 2017 a 63 years old male was examined and the results of the visual field test suggested glaucoma in the right eye. The treatment for normal tension glaucoma was started and continued until a new visual field test was performed over a year later – this time with iCare COMPASS. The results of this test revealed, however, a different diagnosis.

Hygienic and easy-to-clean design

The design of iCare COMPASS offers an additional benefit of being easy to clean between patients due to the smooth, narrow and convex front of the device: no bowl and trial lens assembly. All iCare COMPASS surfaces can be disinfected with an alcohol wipe. Watch the video for more information.
