Two recent studies have demonstrated the Optos Silverstone device – combining ultra-widefield (UWF) fundus capture with optomap-guided swept source-OCT (SS-OCT) – can improve patient management and impact treatment decisions.
The first of these studies was published in International Ophthalmology this year and sought to describe the feasibility of peripheral OCT imaging in retinal diseases using the Silverstone device.
It found that 39 (31%) out of 125 eyes with retinal pathologies had macular pathologies. Eighty-six out of 125 eyes (69%) had peripheral only pathologies, which the researchers described as “an area which cannot be visualised by standard OCT devices with a 50-degree field-of-view”.
The study also found that optomap-guided OCT imaging impacted clinical decision making in 84% of cases, Optos reported.
“The ability to capture peripheral pathologies using integrated (optomap UWF) imaging with full-field swept-source provided anatomical insight that guided medical and surgical management in the majority of cases,” the authors concluded.
“Its use in the mid- and far periphery provides a holistic clinical picture, which can potentially aid in the understanding of various retinal pathologies.”
The second paper, published in the Journal of VitreoRetinal Diseases earlier this year, looked at the clinical significance of peripheral OCT imaging with Silverstone.
The authors found that in 38% of cases, optomap navigated SS-OCT directly contributed to patient management plans (laser, injection or surgical treatment).
In total, 86.4% of the image series were deemed diagnostically significant for the peripheral pathology.
“Navigated UWF SS-OCT imaging was clinically practical and provided high-quality characterisation of peripheral retinal lesions for all eyes,” the researchers stated.
In both studies, the most common findings were: chorioretinal scars, retinal tears and holes, retinoschisis, detachments, retinal tufts, central serous retinopathy (CSR), lattice degeneration, choroidal nevi, vitreous inflammation overlying a peripheral scar, Coats disease, and peripheral retinal traction in sickle cell retinopathy.
