Real-time Eye Tracking and Imaging of the Eye in Diabetic Retinopathy Patients

Diabetic retinopathy (DR) is a leading cause of vision loss in working age Canadians. Current treatment consists of early detection and laser photocoagulation therapy for preventing progressive or severe vision loss. Microaneurysms (MA) are the earliest, clinically visible changes of DR, which are visualized using specialized imaging technologies. PulseMedica is developing a three-dimensional (3D) retinal imaging system with real-time eye tracking capabilities. The purpose of this study is to assess the feasibility of PulseMedica's prototype device, the OSNAT800 Imaging Only (IO), in providing real-time tracking of eye movements in patients with DR. It is hypothesized that the OSNAT 800 IO will be able to perform real-time eye tracking while imaging patients with DR.
