Optos is debuting a new addition to its portfolio of ultrawide-field (UWF) imaging systems: the Silverstone RGB.
Keeping with the theme of product launches this week, the platform will make its debut at the 2025 American Academy of Ophthalmology (AAO) annual meeting.
Wait just a minute … isn’t there already a Silverstone imaging platform?
Indeed, there is. However, as Optos noted, this new platform builds on that of the flagship Silverstone—and adds a few more features and capabilities.
Gotcha. But first, talk about optomap.
Optomap is Optos’s clinically validated, multimodal tool for UWF retinal images that can capture 82% (or 200°) of the retina in a single image capture.
Importantly: This is done via a single—quick—non-invasive image capture.
See here for a look at the company’s UWF imaging product portfolio—including more on how an optomap image is captured
Now let’s discuss the original Silverstone platform.
The original Silverstone platform was first introduced in 2019 (also at AAO) as a “first of its kind … UWF retinal imaging with integrated, image-guided, swept-source (SS) optical coherence tomography (OCT).”
Among its capabilities:
- Producing a 200° single capture optomap image
- Using guided OCT to enable advanced OCT imaging anywhere across the retina
And specifically: The platform combines autofluorescence (AF), fluorescein (FA), and indocyanine green (ICG) angiography with SS-OCT imaging capabilities.
Now to this advanced Silverstone.
Compared to its predecessor, the next-generation platform provides “the broadest spectrum of retinal imaging capabilities,” enabling clinicians to visualize areas of the retina far into the periphery—and to the central pole.
Specifically: Nine modalities are offered in addition to those already available in the original system:
- optomap color rgb (red, green, and blue laser)
- For true-to-life retinal color imaging
- optomap color rg (red and green laser)
- optomap Sensory Retina (green laser)
- For highlighting nerve fibers and vascular structures
- optomap Choroidal (red laser)
- For deep tissue visualization
- optomap green af (green laser)
- For identifying retinal pigment epithelium (RPE) changes and metabolic activity
- optomap blue af (blue laser)
- For visualizing subtle retinal pathology
- optomap fa (blue laser): fluorescein angiography
- For vascular evaluation and disease detection
- optomap icg (infra-red): ICG angiography
- For enhanced choroidal and vascular imaging
- Optomap-navigated peripheral SS-OCT
- For high-resolution imaging anywhere in the retina
With all modalities available in a single device, Optos also noted that the system supports similar geographic atrophy (GA) progression with standard and UWF FAF— ”suggesting either may be used longitudinally, although not interchangeably.”
What else to know?
The Silverstone RGB uses a scanning laser ophthalmoscope (SLO) to penetrate media opacities and allow clinicians to capture clear retinal images, “even through a grade 3+ cataract,” according to its product brochure.
Why this may be valuable: Clinicians can rule out potential retinal pathologies prior to performing anterior segment surgery.
Anything else?
The system also includes:
- 1050 nm OCT light source to provide deeper penetration for clearer and detailed choroidal imaging
- 4-in-1 color depth imaging offers key clinical data from the retinal surface via the choroid.
- Integrated tools such as the AreaAssist allow clinicians to automatically measure continuous areas of matching color and adjust a selected area’s sensitivity
Where can I get the technical specification on this?
See here for details on the system’s:
- Wavelengths (for red, green, and blue lasers as well as infra-red)
- Exposure time
- OCT imaging and scan types
- Physical footprint

Lastly, let’s talk availability.
If you’re at AAO this weekend, stop by the Optos booth (#1842) for a first look.
Otherwise, contact the company to request information on pricing and availability.
