Unlike conventional ophthalmic OCT, robotically aligning OCT (RAOCT) removes the requirement for close patient/operator proximity and enables remote patient imaging by autonomously aligning itself to the patient while the operator is physically elsewhere. We report kilometer-scale distance between OCT operator and patient and the first robotically aligned OCT angiography images. We acquired remote volumetric RAOCT retinal images from healthy and diseased eyes at the Duke Eye Center on both room-to-room (10m between imager and subject) and between clinic sites(>10km between imager and subject). This can serve as a foundation for socially distanced or telehealth retinal OCT without physically present technicians.
The physical distancing requirements necessary to prevent spread of the novel coronavirus, SARS-CoV-2, requires a change in approach for clinical ophthalmic imaging. Conventional optical coherence tomography (OCT) systems require patients to position themselves in chin/forehead rests for stabilization with the system operator in close proximity. We developed a robotically aligning OCT (RAOCT) system that provides volumetric retinal images encompassing both the optic nerve head and fovea. Our RAOCT system self aligned to subjects’ eyes (seated, no contact with restraints), acquired OCT images of both normal and diseased retinas, all with allowing the operator behind a barrier >2 m from the subjects.
