Confocal vs. non-confocal imaging
SLO systems are superior to conventional fundus cameras in many ways, as they exploit a confocal imaging principle which limits the effect of backscattered light from deeper layers and provides enhanced image quality. Another major advantage of SLO systems is that they operate with much smaller pupils than conventional fundus cameras.
Eidon, being a confocal optical system, is able to perform high quality retinal images: increased sharpness, better optical resolution and greater contrast when compared to traditional fundus camera imaging.
This technology captures retinal images of preserved quality even in cases of media opacity.
TrueColor Imaging: What you see is what it is!
Differently from existing SLO systems, EIDON is a scanning ophthalmoscope that uses WHITE light instead of monochromatic lasers, hence providing true color imaging and offering major benefits in terms of fidelity to real retinal appearance, no distortion and dilation-free operation.
The unique combination of confocal imaging and white light illumination offers superior image quality and color fidelity. Using white light, the retina appears as it looks when directly observed, so as the entire visible spectrum is present in the captured image.
The importance of white-light confocal imaging
This particular technology facilitates diagnosis and monitoring of retinal diseases such as diabetic retinopathy, age-related macular degeneration and glaucoma. EIDON improves retinal diagnostics capabilities in that it offers:
Greater contrast than a traditional fundus camera
Preserved image quality in presence of media opacities such as cataract
High resolution images
No dilation down to 2.5 mm pupil
60° field of view in single exposure
No optic disc bleaching
No saturation of the red channel like in traditional fundus cameras
Wide field imaging
Wide field optics allow imaging the central retina as well as the periphery.
Infrared, live viewing of a wide field (out to 110°) is possible using the programmable internal fixation target.
Fixation target can be displaced directly on the touch screen to frame different fields.
An external fixation target is provided, for use in the counter lateral eye: 150° can be reached in manual mode.
Enhancing patient comfort and practice workflow
LED flash technology guarantees maximum patient comfort as it uses a low power light source.
This in turn reduces pupil constriction and facilitates the test on non-cooperative subjects.
