Fundus de perimetría automatizadaDescargar Documento Ver Video Contacte con el director
Compass is the first Fundus Automated perimeter capable of performing standard 24-2 visual field testing, delivering TrueColor confocal images at the same time.
COMPASS is a scanning ophthalmoscope combined with an automatic perimeter that provides confocal images of the retina, as well as measurements of retinal threshold sensitivity, under non-mydriatic conditions.
Fundus automated perimetry is a technique that images the retina during visual field testing, enabling a correlation to be made between visual function and retinal structure.1
Advantages of Fundus Automated Perimetry over Standard Automated Perimetry include the possibility to measure sensitivity at specific retinal locations, higher accuracy thanks to retinal-tracking based compensation of eye movements and the simultaneous assessment of function (expressed by retinal sensitivity) and structure (images of the ONH, of the RNFL and of the retina). Fundus Automated Perimetry provides a simultaneous, quantitative assessment of fixation characteristics.
Use of Fundus Automated Perimetry in the clinical management of glaucoma has been limited so far, as available systems were lacking compliance with the standards of automated perimetry. COMPASS overcomes such limitations and brings visual field analysis to the next level!
In particular COMPASS, for the first time, extends field coverage to 30° + 30° and employs luminance parameters and a sensitivity scale as used in standard automated perimetry.
High-resolution TrueColor Confocal Imaging of the ONH, of the RNFL and of central retina
Combined structure and function analysis
High test – retest repeatability thanks to the Real Time Retinal Tracking, that actively compensates eye movements
Reliable automated follow up with combined structure-function progression analysis
Operator friendly: no trials lens required, automatic refractive correction
More patient comfort: test can be suspended at any time without data loss
