dc.description.abstractmobileVision is a portable, robust, smartphone-based ophthalmoscopy system intended to reduce the barriers to ocular pathology screening in developing and underserved regions. Through smartphone integration and ergonomic design, the system demonstrates automatic compensation for patient refractive error, voice-activated multi-shot retinal image acquisition without pupil dilation, and touch-gesture based control of patient fixation and accommodation. Further, a lucky imaging and retinal stitching pipeline is developed and demonstrated, which not only increases overall retinal field-of-view, but also makes the system robust to patient saccades, blinks, device jitter, and imaging artifacts such as noise or unintended scattering from ocular surfaces. The prototype is tested through a combination of mock eye tests and in-vivo trials. The current prototype can image over +/-45 degrees of retina with an estimated 23.5 um of retinal resolution for patients with between -6D to +13D refractive error.
