Description

Optos Silverstone OCT device solves many of these problems. This multimodal platform integrates fundus imaging with an ultra-wide field of view (200 degrees in a single scan), wide-angle swept-source OCT (SS-OCT), fundus autofluorescence (FAF), fluorescein angiography and indocyanine angiography.

The technology available at Silverstone creates new possibilities in supporting clinical decision-making and streamlines the research process. Key image data facilitate work and increase the accuracy of diagnoses. A helpful tool is the possibility of simultaneous analysis of peripheral OCT scans and ultra-wide-angle retinal imaging.

 

To verify the usefulness of ultra-wide-angle SLO and OCT imaging, a study was carried out on the possibility of peripheral OCT imaging using a novel, integrated SLO (“Feasibility of peripheral OCT imaging using a novel integrated SLO ultra-widefield imaging swept-source OCT device,” Simrat device) K. Sodhi, John Golding, Carmelina Trimboli Netan Choudhry; International Ophthalmology (2021)).

In a single-center, prospective observation presented at The Macula Society meeting in 2021, 134 eyes were imaged with the Optos Silverstone OCT. Scanning laser ophthalmoscope images (optomaps, autofluorescence) and related SS-OCT images were obtained in the posterior pole, at the far or medium circumference (depending on the nature of the patient’s referral and the areas of interest observed on the wide-angle optomap images during the examination).

A total of 134 eyes (96 patients) were included in the study. 125 eyes (91 patients) with 38 retinal pathologies were prospectively assessed, and 9 eyes (5 patients) were excluded due to incomplete image acquisition. The mean age of the respondents was 54 years (range 21-92 years). Thirty-nine of 125 eyes (31%) had macular pathology. Eighty-six of the 125 eyes (69%) had purely peripheral pathology in an area that cannot be visualized with standard 50-degree OCT devices. Of the 125 photographed eyes, 86 (69%) had pathology present only in the periphery. Among them, the addition of peripheral OCT influenced clinical decision-making in 72 eyes (84%)

Optos Silverstone 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 critical clinical data from the retinal surface through the choroid

Image Modalities:

  • optomap color and optomap plus (red and green laser):
    Color composite view
    Green laser view
    Red laser view
  • optomap af (green laser): autofluorescence
  • optomap fa (blue laser): fluorescein angiography
  • optomap icg (infra-red): indocyanine green angiography
  • Swept-Source Optical Coherence Tomography (OCT

It allows viewing all captured images (color, FFAICGOCT ) in a single composite image. It provides ophthalmologists with a single contactless optomap view with UWF digital images of 200 degrees or 82% of the retina. It offers the opportunity to take 23 mm OCT with a single touch at any point you specify on your 200° color Optomap image. At the same time, it produces an unrivaled sharp 200° single capture AF Autofluorescence image.

This fast, easy, patient-friendly, ultra-widefield imaging technology is designed for eye scanning and has been shown to improve practice flow and patient engagement. It allows easy 200° fundus imaging and ROP examination regardless of age in pediatric patients. It comes with OptosAdvance™ browser-based image review software allows for simple documentation, monitoring, and referral to aid patient management and improved patient flow.

Despite high cataracts and vitreous opacities, you can get 200° clear images. You can get  200° clear pictures even from a 2mm pupil opening, and you can provide 3D imaging.
