Significantly more medical students were able to visualize the optic nerve with the smartphone ophthalmoscope vs the direct ophthalmoscope in an undilated pupil (82.3% vs 48.5%, P<0.0001). Students reported a more positive experience with the smartphone ophthalmoscope, specifically regarding ease of use (median of 4 vs 3; P<0.0001), their confidence in performing ophthalmoscopy (median of 4 vs 3; P<0.0001), and their ability to visualize features of the optic nerve (median 4 vs 3; P<0.0001). A significant number of participants preferred the smartphone ophthalmoscope over the traditional direct ophthalmoscope for learning how to identify the optic disc and for evaluating patients (78.2% and 77.2%, respectively; P<0.0001).Conclusion: Smartphone ophthalmoscopy may serve as a useful adjunctive tool to teach direct ophthalmoscopy as well as being an alternative for examining the fundus for noneye care physicians.
