Design outcomes

Primary

Measure	Time frame
For each of the adult and pediatric eye models, two ophthalmologists independently evaluated whether the stored videos by study participants were of diagnostic value or not.	—

Secondary

Measure	Time frame
(A) For each of the adult and pediatric eye models, two ophthalmologists independently evaluate the stored video quality (i) and (ii). (i) Overall image quality (3-point scale: excellent, fair, and poor) Excellent: the entire posterior pole is in focus. The posterior pole includes the retina between the optic nerve papilla and the arcade vessels, the macula and the optic nerve papilla. Acceptable: too bright, too dark, or out of focus but sufficient to determine the presence or absence of a lesion Impossible: out of focus or obscured by reflections or artifacts. (ii) Accuracy of depiction of each anatomic merkmal (optic nerve papilla, macula, upper arcade vessels, lower arcade vessels) (3-point scale: not visible, visible but image quality is poor, visible and image quality is adequate) (iii) Percentage of correct diagnosis by the study participants (iv) Inter-rater agreement rate between the two opthalmologists (B) Comparison between adult and pediatric eye models for all the above items	—
