iCare COMPASS Automated Perimeter with Active Retinal Tracking

iCare COMPASS combines visual field tests, fixation loss correction by a real-time retinal tracker and confocal TrueColor fundus imaging taking visual field analysis to the next level. With touch screen, auto-alignment, non-mydriatic, easy-to-disinfect, and trial lens-free operation, iCare COMPASS is patient-friendly and easy to use, saving time and helping in improving clinical performance.

iCare COMPASS is the first automated perimeter that can perform standard visual field tests using a real-time retinal tracker while delivering ultra-high-resolution confocal TrueColor fundus images at the same time.


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, automated, tracking of eye movements by infrared scanning of the retina provides active compensation for fixation losses, with perimetric stimuli automatically re-positioned 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 resulting in the reduction of motion artifacts.

Automated visual field test with TrueColor confocal imaging

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.

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

With iCare COMPASS Automatic Refraction Correction, the Auto-focus, there is no need for trial lenses. This not only reduces 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 too. iCare COMPASS also offers embedded capabilities for network connectivity that allows remote viewing.
