We demonstrated a contact handheld ultra-widefield (UWF) swept-source OCT (SS-OCT) imaging system with a 400 kHz VCSEL light source that achieved an unprecedented 140° field of view (FOV), which was capable to extend the imaging area from the posterior pole to peripheral retina in a single shot. The contact imaging approach provided faster and more efficient retinal imaging and improve image quality. To the best of our knowledge, this prototype achieved the widest FOV among all the retinal OCT research prototypes and commercial systems in desktop and portable format.
