We introduced an improved iteration of a panoramic retinal (panretinal) handheld swept-source OCT angiography (OCTA) imaging system with an 800kHz VCSEL light source. The advanced system successfully achieved a remarkable 140° field of view (FOV, visual angle measured from the pupil plane), enabling comprehensive imaging coverage from the posterior pole to the peripheral retina in a single capture.
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.
We demonstrated a handheld swept-source optical coherence tomography (OCT) imaging system with a 400 kHz vertical-cavity surface-emitting laser (VCSEL) light source, a non-contact approach, and an unprecedented 105° field of view (FOV) that was capable of obtaining images from the posterior pole to peripheral retina in a single shot. A spiral scanning pattern allowing real-time visualization was also implemented here to improve the sampling efficiency. To the best of our knowledge, this is the widest FOV for a portable non-contact OCT retinal imaging system to date. Improvements to the FOV allow detection of peripheral pathology and aid better understanding of the role of peripheral pathology in retinal diseases.
