As the popularity of ultra-widefield imaging grows and the technology becomes more commonplace, retinal specialists can use it to help with diagnosis and management decisions, said Charles C. Wykoff, MD, PhD.
“It’s a more complete view of the back of the eye,” said Dr. Wykoff, Retina Consultants of Houston, Houston. However, he added, it doesn’t replace a thorough clinical examination.
The advantage of using ultra-widefield imaging is its ability to capture more of the posterior segment than has been possible with traditional fundus photography.
The latest imaging technology (OptosAdvance, Optos) captures 200°, or 82%, of the retina in one image. The device has six imaging modes, including three-in-one color depth imaging, angiography, and autofluorescence. The device is also on a HIPAA-compliant, cloud-enabled platform so users can see images from any networked device.
“By definition, ultra-widefield images show a minimum of 80% of the retina and include key peripheral landmarks, such as the vortex ampullae,” said Carole McCallum, director of ophthalmology marketing, Optos.
Dr. Wykoff, who has used ultra-widefield imaging for more than six years, sees key advantages for the incorporation of ultra-widefield imaging into clinical practice. It can help guide the management of retinal vascular diseases including retinal venous occlusive disease and diabetic retinopathy (DR).
With ultra-widefield imaging, more pathology is often visible peripherally, Dr. Wykoff said.
