Journal Article
New 200° Single-Capture Color Red-Green-Blue Ultra-Widefield Retinal Imaging Technology: First Clinical Experience
2023
Overview
Background and Objective:
We investigated the additive clinical benefits of a new ultra-widefield (UWF) red-green-blue (RGB) imaging technology.
Patients and Methods:
This was a retrospective, observational, single-center study of 86 consecutive patients (172 eyes). UWF red-green (RG) and RGB images were taken using a new Optos California (Optos Plc). This scanning laser ophthalmoscope uses wavelengths of 635 nm, 532 nm, and 488 nm for the red (R), green (G), and blue laser (B), respectively. The same device can image both in UWF RG and RGB simultaneously.
Results:
The new Optos California provides a well-balanced, three-channel color image that is clinically useful in imaging and identifying vitreoretinal, retinal, and chorioretinal pathologies. The combination of the images captured by each laser source produces a final composite image that more accurately reflects the natural colors of the fundus. The addition of blue light provides additional detail to visualize the vitreoretinal interface and superficial retina, both within the posterior pole and in the periphery.
Conclusions:
This new device allows for both RG and RGB imaging of the retina, providing valuable information on the anatomy of the vitreoretinal interface, retina, retinal pigment epithelium, and their abnormalities. Both techniques complement each other and can be useful in daily practice, allowing clinicians to choose the preferred imaging technique depending on specific findings and conditions.
