Oct Ophthalmoscope

The sole ultra-widefield imaging device with an integrated swept source OCT is Silverstone, the most potent tool available for retinal examination. The Silverstone system generates a 200° single-capture retinal image of unparalleled clarity in less than ½ second and facilitates optomap-guided OCT scanning across the retina and into the far periphery. input:
output:The following advantages are provided by Silverstone:
The retina-vitreous-sclera detailed examination is facilitated by the integrated swept-source OCT in UWF.

Pathology can be imaged on the optomap using UWF-guided, swept-source OCT.

A 1050 nm OCT light source is employed to achieve clear, detailed choroidal imaging by allowing for deeper tissue penetration.

3-in-1 Color Depth ImagingTM offers critical clinical information from the retinal surface to the choroid.Technical SpecificationsImage Modalities
