Evaluating medical students’ proficiency with a handheld ophthalmoscope: a pilot study

Figures & data

Figure 1 A selection of nine randomized photos from 16 standardized patients were laid out on a grid and numbered with a random letter-combination.

Figure 2 Clicking on a photo could deselect it to remove it from consideration.
