![]() Above, right: a sample Eidon wide-field image mosaic. The Eidon confocal scanner can scan with white light, resulting in a true-color image (above far left, compared to the same scan taken using scanning laser ophthalmoscopy, producing a pseudo-color image). It supports multi-field acquisitions covering up to 110 degrees in automatic mode and 150 degrees in manual mode. ![]() an exam time less than 30 seconds per eye for a single field.a compact, small-footprint design with standalone operation and.automatic alignment with the patient’s pupil and retinal focus.the ability to run in fully automated or manual modes.the ability to image through cataract and media opacities.non-mydriatic operation (2.5 mm minimum pupil size).infrared and red-free confocal image options, presented with super-high resolution and contrast.Other benefits of the Eidon, according to Centervue, include: (See example, facing page.) Centervue says that white-light illumination reveals greater detail of retinal pathologies and allows a clearer view of the optic nerve. The merging of color channels in that approach results in a bright orange retinal image, blood having a blue-green hue, and a dark or black optic nerve. According to the manufacturer, Eidon is the only wide-view system that combines confocal imaging with natural white-light illumination to provide a true-color image, as opposed to the pseudo-color rendering generated by monochromatic lasers in scanning laser ophthalmoscope-based systems. The Eidon confocal scanner (Centervue, Padova, Italy) received FDA clearance in December 2014. Here, we review the features offered by each device, with comments from ophthalmologists who have used them in the clinic. One is the latest iteration of Optos’s wide-field scanning devices the other is a new instrument from Italy that allows true-color retinal imaging. In the past six months, two new instruments designed to provide high-resolution views of the retina have been approved by the Food and Drug Administration.
