Optical Path Redirection Device for Optical Coherence Tomography Angiography of Recumbent Patients Under General Anesthesia

PURPOSE: Optical coherence tomography angiography is useful for the noninvasive imaging of retinal and choroidal vasculature, but some patients are unable to cooperate for imaging in clinic. We created a device that allows for imaging in the recumbent position under anesthesia. METHODS: A three-dime...

description PURPOSE: Optical coherence tomography angiography is useful for the noninvasive imaging of retinal and choroidal vasculature, but some patients are unable to cooperate for imaging in clinic. We created a device that allows for imaging in the recumbent position under anesthesia. METHODS: A three-dimensional printed prototype was designed to attach to the Optovue AngioVue. Within the device, a right-angled mirror was positioned to redirect the optical path of the optical coherence tomography angiography machine downward into the eye of a recumbent, intubated patient. RESULTS: Three image sequences were successfully performed using the first test device. The image clarity was adequate, but the field of view was limited, potentially owing to an increased distance between the subject's pupil and the lens of the machine or obstruction of the optical path from the attachment device. CONCLUSIONS: A right-angled mirror system is a viable solution for imaging patients who require sedation to obtain readable images. TRANSLATIONAL RELEVANCE: This system will allow for broader study of optical coherence tomography angiography imaging features, especially in children, by adapting the Optovue AngioVue for use in recumbent patients under anesthesia.
