Optos Silverstone - Ultra-widefield Imaging Device

Silverstone offers the following benefits:

• UWF with integrated swept-source OCT, facilitates detailed examination of the retina-vitreous to sclera
• UWF guided, swept-source OCT, images pathology anywhere on the optomap
• 1050 nm OCT light source, provides deeper tissue penetration for clear, detailed choroidal imaging
• 3-in-1 Color Depth ImagingTM provides important clinical data from the retinal surface through the choroid
