Studies back UWF-SS OCT
UWF-guided OCT enables OCT capture including in the far periphery

Studies back UWF-SS OCT

Two recent, independent studies have shown that Optos’ Silverstone retinal scanning system can improve patient management and alter treatment decisions.

 

The first study¹ by researchers from the Department of Ophthalmology’s retina service at Weill Cornell Medical College, New York, found the combined ultra-widefield (UWF) swept-source optical coherence tomography (UWF SS-OCT) imaging system was clinically practical and provided high-quality characterisation of peripheral retinal lesions in a 72-patient study (82 eyes) aged from 8-87 years (average 59.4). “Images directly contributed to management plans, including laser, injection or surgical treatment, for a clinically meaningful set of patients (38%),” reported authors in the Journal of Vitreoretinal Diseases.

 

The second study² by a combined team from Cambridge University in the UK and Vitreous Retina Macula Specialists of Toronto, Canada, delved further into the usefulness of peripheral OCT imaging for retinal diseases in a study spanning 91 patients (125 eyes) aged from 21–92 years (average 54). Reporting their results in International Ophthalmology, researchers found that 69% had peripheral-only pathologies, including retinal tears and holes, retinoschisis and retinal detachment, retinal tuft, central serous retinopathy, lattice degeneration and choroidal nevus. “In 39 out of 125 eyes (31%), the pathology was located in the posterior pole, and while the images were acquired, these pathologies would have been captured by standard OCT devices with a 50⁰ degree field of view,” they wrote, concluding the system provided high-grade anatomical insight. “Its use in the mid- and far periphery provides a holistic clinical picture, which can potentially aid in the understanding of various retinal pathologies.”
